It applies trained rules without reasoning independently. This means quality input yields quality output, while poor input leads to poor results. Additionally, its training data limits its knowledge to specific timeframes, making it unreliable for new or niche topics.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Effective Use of ChatGPT<\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Understanding Code<\/strong><br>LLMs can analyze unfamiliar code, making it easier for developers\u2014especially juniors\u2014to understand and modify. For instance, asking ChatGPT to explain a function often provides a clear breakdown.<\/li>\n\n\n\n<li><strong>Code Suggestions<\/strong><br>Tools like GitHub Copilot excel in contextualizing code, analyzing your editor and repository to provide relevant suggestions. These tools surpass generic LLMs in specificity.<\/li>\n\n\n\n<li><strong>Writing Tests<\/strong><br>Test creation is a critical skill that takes time to master. LLMs can generate initial test cases, saving time and ensuring better code coverage.<\/li>\n\n\n\n<li><strong>Improving Security<\/strong><br>ChatGPT can identify potential vulnerabilities and suggest improvements, such as adding parameter validations or null checks.<\/li>\n\n\n\n<li><strong>Refactoring Code<\/strong><br>Refactoring suggestions from LLMs improve readability and maintainability. Although not always performance-optimized, they often provide a clearer structure.<\/li>\n\n\n\n<li><strong>Generating Boilerplate Code<\/strong><br>Starting new projects or functionalities often involves repetitive tasks. ChatGPT can generate boilerplate code tailored to your needs, reducing setup time.<\/li>\n\n\n\n<li><strong>Adding Comments<\/strong><br>LLMs can automatically add detailed comments to your code, making it easier to understand and maintain, especially for undocumented or legacy systems.<\/li>\n\n\n\n<li><strong>Code Reviews<\/strong><br>GitHub Actions like ChatGPT Code Reviewer automate pull request reviews, providing actionable insights and improving the quality of contributions.<\/li>\n\n\n\n<li><strong>Documentation and Translation<\/strong><br>LLM-powered tools simplify documentation and even automate translations, making collaboration across teams seamless.<\/li>\n<\/ol>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">LLMs Are Not Designed for Problem Solving or Riddles<\/h3>\n\n\n\n<p>LLMs are built to answer questions, write articles, and generate code, not to solve problems or riddles. If you present an unsolved problem to an LLM, it won&#8217;t be able to solve it. However, if you provide a solved problem, the model can explain or reproduce the solution.<\/p>\n\n\n\n<p>Watching someone present a riddle to ChatGPT and then being surprised when it fails to solve it is akin to asking a 5-year-old to tackle quantum physics\u2014such tests ignore the tool&#8217;s design and capabilities. They don\u2019t prove the model is inadequate but rather highlight the user&#8217;s misunderstanding of how to utilize it.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Knowledge Limitations<\/h3>\n\n\n\n<p>LLMs have finite knowledge restricted to the data in their training sets. If you ask about a topic not included in its dataset, the model can&#8217;t provide an accurate answer.<\/p>\n\n\n\n<p>When does this limitation become obvious?<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>When asking about products, technologies, or events that didn\u2019t exist or were newly introduced during the model&#8217;s training phase.<\/li>\n<\/ul>\n\n\n\n<p>While mitigations like real-time web queries and continuous training are emerging, these are partial solutions. Models may still produce low-quality or fabricated responses about recent developments.<\/p>\n\n\n\n<p><strong>Don&#8217;t expect reliable answers from ChatGPT on newly released products, technologies, or recent events.<\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Where Results Improve<\/h3>\n\n\n\n<p>Some models, like GitHub Copilot, surpass prompt-only LLMs by leveraging additional context, such as analyzing the code around the cursor, open files, and linked GitHub repositories. This broader context allows Copilot to produce more accurate and relevant suggestions.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Example: Contextual Code Suggestion<\/h4>\n\n\n\n<p>Given the following code:<\/p>\n\n\n<pre class=\"wp-block-code\" aria-describedby=\"shcb-language-1\" data-shcb-language-name=\"PHP\" data-shcb-language-slug=\"php\"><span><code class=\"hljs language-php\">java&lt;code&gt;<span class=\"hljs-keyword\">public<\/span> <span class=\"hljs-keyword\">static<\/span> <span class=\"hljs-keyword\">final<\/span> int UNO = <span class=\"hljs-number\">1<\/span>;  \n<span class=\"hljs-keyword\">public<\/span> <span class=\"hljs-keyword\">static<\/span> <span class=\"hljs-keyword\">final<\/span> int DUE = <span class=\"hljs-number\">2<\/span>;  \n<span class=\"hljs-comment\">\/\/ Other static variables  <\/span>\n\n<span class=\"hljs-keyword\">public<\/span> <span class=\"hljs-keyword\">static<\/span> void main(String&#91;] args) {  \n    <span class=\"hljs-comment\">\/\/ Find a match for the parameter in the static values  <\/span>\n}  \n&lt;\/code&gt;<\/code><\/span><small class=\"shcb-language\" id=\"shcb-language-1\"><span class=\"shcb-language__label\">Code language:<\/span> <span class=\"shcb-language__name\">PHP<\/span> <span class=\"shcb-language__paren\">(<\/span><span class=\"shcb-language__slug\">php<\/span><span class=\"shcb-language__paren\">)<\/span><\/small><\/pre>\n\n\n<p>This vague comment wouldn\u2019t yield useful results with ChatGPT.

LLMs assist by explaining what code does and how it works.<\/p>\n\n\n\n<p>For instance, given the following function:<\/p>\n\n\n<pre class=\"wp-block-code\" aria-describedby=\"shcb-language-3\" data-shcb-language-name=\"JavaScript\" data-shcb-language-slug=\"javascript\"><span><code class=\"hljs language-javascript\">java&lt;code&gt;public <span class=\"hljs-keyword\">static<\/span> boolean matchesURI(URI uri1, URI uri2) {  \n    <span class=\"hljs-built_in\">String<\/span> scheme = uri1.getScheme();  \n    <span class=\"hljs-keyword\">if<\/span> (scheme.equalsIgnoreCase(uri2.getScheme())) {  \n        <span class=\"hljs-keyword\">if<\/span> (uri1.getHost().equalsIgnoreCase(uri2.getHost())) {  \n            int thisPort = HttpClient.normalizePort(scheme, uri1.getPort());  \n            int thatPort = HttpClient.normalizePort(scheme, uri2.getPort());  \n            <span class=\"hljs-keyword\">if<\/span> (thisPort == thatPort) {  \n                <span class=\"hljs-keyword\">return<\/span> uri2.getPath().startsWith(uri1.getPath());  \n            }  \n        }  \n    }  \n    <span class=\"hljs-keyword\">return<\/span> <span class=\"hljs-literal\">false<\/span>;  \n}  \n&lt;<span class=\"hljs-regexp\">\/code&gt;<\/span><\/code><\/span><small class=\"shcb-language\" id=\"shcb-language-3\"><span class=\"shcb-language__label\">Code language:<\/span> <span class=\"shcb-language__name\">JavaScript<\/span> <span class=\"shcb-language__paren\">(<\/span><span class=\"shcb-language__slug\">javascript<\/span><span class=\"shcb-language__paren\">)<\/span><\/small><\/pre>\n\n\n<p>When asked to describe the function, an LLM might respond:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Compares the schemes (protocols) of two URIs.<\/li>\n\n\n\n<li>Matches hosts and normalized ports.<\/li>\n\n\n\n<li>Checks if one URI&#8217;s path starts with the other&#8217;s path.<\/li>\n<\/ul>\n\n\n\n<p>This concise explanation helps developers understand complex or poorly documented code.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Test Creation<\/h3>\n\n\n\n<p>Writing tests can be challenging, especially for juniors. LLMs can generate test cases for a function, providing a foundation for robust testing. For example:<\/p>\n\n\n<pre class=\"wp-block-code\" aria-describedby=\"shcb-language-4\" data-shcb-language-name=\"JavaScript\" data-shcb-language-slug=\"javascript\"><span><code class=\"hljs language-javascript\">java&lt;code&gt;@Test  \npublic <span class=\"hljs-keyword\">void<\/span> testMatchingURIs() {  \n    URI uri1 = <span class=\"hljs-keyword\">new<\/span> URI(<span class=\"hljs-string\">\"http:\/\/example.com\/path\"<\/span>);  \n    URI uri2 = <span class=\"hljs-keyword\">new<\/span> URI(<span class=\"hljs-string\">\"http:\/\/example.com\/path\/subpath\"<\/span>);  \n    assertTrue(URIMatcher.matchesURI(uri1, uri2));  \n}  \n\n@Test  \npublic <span class=\"hljs-keyword\">void<\/span> testNonMatchingScheme() {  \n    URI uri1 = <span class=\"hljs-keyword\">new<\/span> URI(<span class=\"hljs-string\">\"http:\/\/example.com\/path\"<\/span>);  \n    URI uri2 = <span class=\"hljs-keyword\">new<\/span> URI(<span class=\"hljs-string\">\"https:\/\/example.com\/path\"<\/span>);  \n    assertFalse(URIMatcher.matchesURI(uri1, uri2));  \n}  \n&lt;<span class=\"hljs-regexp\">\/code&gt;<\/span><\/code><\/span><small class=\"shcb-language\" id=\"shcb-language-4\"><span class=\"shcb-language__label\">Code language:<\/span> <span class=\"shcb-language__name\">JavaScript<\/span> <span class=\"shcb-language__paren\">(<\/span><span class=\"shcb-language__slug\">javascript<\/span><span class=\"shcb-language__paren\">)<\/span><\/small><\/pre>\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Refactoring for Clarity<\/h3>\n\n\n\n<p>LLMs can also help refactor code for readability and maintainability:<\/p>\n\n\n\n<p>Original code:<\/p>\n\n\n<pre class=\"wp-block-code\" aria-describedby=\"shcb-language-5\" data-shcb-language-name=\"JavaScript\" data-shcb-language-slug=\"javascript\"><span><code class=\"hljs language-javascript\">java\n&lt;code&gt;<span class=\"hljs-keyword\">if<\/span> (uri1.getHost().equalsIgnoreCase(uri2.getHost())) {  \n    <span class=\"hljs-keyword\">if<\/span> (port1 == port2) {  \n        <span class=\"hljs-keyword\">if<\/span> (path2.startsWith(path1)) {  \n            <span class=\"hljs-keyword\">return<\/span> <span class=\"hljs-literal\">true<\/span>;  \n        }  \n    }  \n}  \n<span class=\"hljs-keyword\">return<\/span> <span class=\"hljs-literal\">false<\/span>;  \n&lt;<span class=\"hljs-regexp\">\/code&gt;<\/span><\/code><\/span><small class=\"shcb-language\" id=\"shcb-language-5\"><span class=\"shcb-language__label\">Code language:<\/span> <span class=\"shcb-language__name\">JavaScript<\/span> <span class=\"shcb-language__paren\">(<\/span><span class=\"shcb-language__slug\">javascript<\/span><span class=\"shcb-language__paren\">)<\/span><\/small><\/pre>\n\n\n<p>Refactored:<\/p>\n\n\n<pre class=\"wp-block-code\" aria-describedby=\"shcb-language-6\" data-shcb-language-name=\"JavaScript\" data-shcb-language-slug=\"javascript\"><span><code class=\"hljs language-javascript\">java\n&lt;code&gt;<span class=\"hljs-keyword\">if<\/span> (!uri1.getHost().equalsIgnoreCase(uri2.getHost())) <span class=\"hljs-keyword\">return<\/span> <span class=\"hljs-literal\">false<\/span>;  \n<span class=\"hljs-keyword\">if<\/span> (port1 != port2) <span class=\"hljs-keyword\">return<\/span> <span class=\"hljs-literal\">false<\/span>;  \n<span class=\"hljs-keyword\">return<\/span> path2.startsWith(path1);  \n&lt;<span class=\"hljs-regexp\">\/code&gt;<\/span><\/code><\/span><small class=\"shcb-language\" id=\"shcb-language-6\"><span class=\"shcb-language__label\">Code language:<\/span> <span class=\"shcb-language__name\">JavaScript<\/span> <span class=\"shcb-language__paren\">(<\/span><span class=\"shcb-language__slug\">javascript<\/span><span class=\"shcb-language__paren\">)<\/span><\/small><\/pre>\n\n\n<p>Though the logic remains the same, the refactored version is easier to read and debug.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Writing Effective Prompts<\/h3>\n\n\n\n<p>The key to using LLMs effectively is crafting clear and precise prompts. But what does that actually mean? Writing a good prompt involves providing explicit instructions on what you expect from the model and what outcome you want.<\/p>\n\n\n\n<p>Here are some basic but essential guidelines:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Be clear and concise.<\/strong><\/li>\n\n\n\n<li><strong>Be specific.<\/strong><\/li>\n\n\n\n<li><strong>Include context and necessary details.<\/strong><\/li>\n\n\n\n<li><strong>Define input and output expectations.<\/strong><\/li>\n<\/ul>\n\n\n\n<p>When applied to programming, these principles may seem straightforward, but creating clear, specific, and concise instructions for a software project is challenging and requires experience with best practices. The more complex a project becomes, the harder it is to distill it into a well-defined prompt.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Real-World Challenges<\/h4>\n\n\n\n<p>Have you ever encountered project specifications that changed over time, were unclear, or lacked the necessary details? Or written code without fully understanding the client\u2019s expectations? In such cases, asking an LLM to deliver exactly what the client wants is almost impossible.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">What Makes a Good Prompt?<\/h3>\n\n\n\n<p>A giant, overly detailed prompt is impractical, but a prompt that\u2019s too short or vague won\u2019t yield the desired results. The solution is to craft prompts that are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>As specific as possible.<\/li>\n\n\n\n<li>Contextually rich yet concise.<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Example: A Clear and Focused Prompt<\/h4>\n\n\n\n<p><em>&#8220;Write a C# function to calculate the factorial of a given number.&#8221;<\/em><\/p>\n\n\n\n<p>This prompt specifies:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>The programming language.<\/li>\n\n\n\n<li>The functionality required.<\/li>\n\n\n\n<li>The input and output expectations.<\/li>\n<\/ol>\n\n\n\n<p>Such a prompt allows the model to produce an accurate and effective response.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Context Matters<\/h3>\n\n\n\n<p>LLMs rely on context to improve results. For example, entering a problem commonly encountered by other programmers increases the chances of obtaining a good solution. However, for highly specific or niche problems, even with sufficient details, the model may struggle.<\/p>\n\n\n\n<p>In such cases, tools like GitHub Copilot, which analyze surrounding code and provide tailored suggestions, might be a better fit.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">Commenting Code<\/h3>\n\n\n\n<p>How many times have you written code without adding comments? Or had to comment someone else\u2019s code but struggled to understand it?<\/p>\n\n\n\n<p>LLMs can help generate comments by starting with a generic prompt like:<br><em>&#8220;Add comments to the following code:&#8221;<\/em><\/p>\n\n\n\n<p>For example, given this code:<\/p>\n\n\n<pre class=\"wp-block-code\" aria-describedby=\"shcb-language-7\" data-shcb-language-name=\"JavaScript\" data-shcb-language-slug=\"javascript\"><span><code class=\"hljs language-javascript\">private <span class=\"hljs-built_in\">String<\/span> readFile(<span class=\"hljs-built_in\">String<\/span> fileName) {  \n    BufferedReader br;  \n    <span class=\"hljs-keyword\">try<\/span> {  \n        br = <span class=\"hljs-keyword\">new<\/span> BufferedReader(<span class=\"hljs-keyword\">new<\/span> FileReader(fileName));  \n        final StringBuilder sb = <span class=\"hljs-keyword\">new<\/span> StringBuilder();  \n        <span class=\"hljs-built_in\">String<\/span> line = br.readLine();  \n\n        <span class=\"hljs-keyword\">while<\/span> (line != <span class=\"hljs-literal\">null<\/span>) {  \n            sb.append(line);  \n            sb.append(System.lineSeparator());  \n            line = br.readLine();  \n        }  \n        br.close();  \n        <span class=\"hljs-keyword\">return<\/span> sb.toString();  \n    } <span class=\"hljs-keyword\">catch<\/span> (IOException e) {  \n        e.printStackTrace();  \n    }  \n    <span class=\"hljs-keyword\">return<\/span> <span class=\"hljs-string\">\"\"<\/span>;  \n}  <\/code><\/span><small class=\"shcb-language\" id=\"shcb-language-7\"><span class=\"shcb-language__label\">Code language:<\/span> <span class=\"shcb-language__name\">JavaScript<\/span> <span class=\"shcb-language__paren\">(<\/span><span class=\"shcb-language__slug\">javascript<\/span><span class=\"shcb-language__paren\">)<\/span><\/small><\/pre>\n\n\n<p>An LLM could generate the following detailed comments:<\/p>\n\n\n<pre class=\"wp-block-code\" aria-describedby=\"shcb-language-8\" data-shcb-language-name=\"PHP\" data-shcb-language-slug=\"php\"><span><code class=\"hljs language-php\"><span class=\"hljs-comment\">\/**  \n * Reads the content of a file and returns it as a string.  \n * <span class=\"hljs-doctag\">@param<\/span> fileName The name of the file to read.  \n * <span class=\"hljs-doctag\">@return<\/span> The file content as a string, or an empty string if an error occurs.  \n *\/<\/span>  \n<span class=\"hljs-keyword\">private<\/span> String readFile(String fileName) {  \n    BufferedReader br;  \n    <span class=\"hljs-keyword\">try<\/span> {  \n        <span class=\"hljs-comment\">\/\/ Initialize a BufferedReader to read the file.  <\/span>\n        br = <span class=\"hljs-keyword\">new<\/span> BufferedReader(<span class=\"hljs-keyword\">new<\/span> FileReader(fileName));  \n\n        <span class=\"hljs-comment\">\/\/ Create a StringBuilder to construct the file content.  <\/span>\n        <span class=\"hljs-keyword\">final<\/span> StringBuilder sb = <span class=\"hljs-keyword\">new<\/span> StringBuilder();  \n\n        <span class=\"hljs-comment\">\/\/ Read the first line of the file.  <\/span>\n        String line = br.readLine();  \n\n        <span class=\"hljs-comment\">\/\/ Continue reading until there are no more lines.  <\/span>\n        <span class=\"hljs-keyword\">while<\/span> (line != <span class=\"hljs-keyword\">null<\/span>) {  \n            <span class=\"hljs-comment\">\/\/ Add the current line to the StringBuilder.  <\/span>\n            sb.append(line);  \n\n            <span class=\"hljs-comment\">\/\/ Add a system-specific line separator.  <\/span>\n            sb.append(System.lineSeparator());  \n\n            <span class=\"hljs-comment\">\/\/ Read the next line.  <\/span>\n            line = br.readLine();  \n        }  \n\n        <span class=\"hljs-comment\">\/\/ Close the BufferedReader.  <\/span>\n        br.close();  \n\n        <span class=\"hljs-comment\">\/\/ Return the file content as a string.  <\/span>\n        <span class=\"hljs-keyword\">return<\/span> sb.toString();  \n    } <span class=\"hljs-keyword\">catch<\/span> (IOException e) {  \n        <span class=\"hljs-comment\">\/\/ Handle any I\/O errors.  <\/span>\n        e.printStackTrace();  \n    }  \n\n    <span class=\"hljs-comment\">\/\/ Return an empty string if an error occurs.  <\/span>\n    <span class=\"hljs-keyword\">return<\/span> <span class=\"hljs-string\">\"\"<\/span>;  \n}  <\/code><\/span><small class=\"shcb-language\" id=\"shcb-language-8\"><span class=\"shcb-language__label\">Code language:<\/span> <span class=\"shcb-language__name\">PHP<\/span> <span class=\"shcb-language__paren\">(<\/span><span class=\"shcb-language__slug\">php<\/span><span class=\"shcb-language__paren\">)<\/span><\/small><\/pre>\n\n\n<p>This process transforms unstructured, undocumented code into something much clearer and more maintainable. Even for simple examples, LLMs can provide significant value in improving code readability and helping developers manage unfamiliar codebases.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Translations<\/h3>\n\n\n\n<p>One of the most annoying tasks a programmer can face is translating project documentation into another language. It&#8217;s a tedious job that requires time and attention but it is necessary to make the project understandable to those who don\u2019t speak our language.<\/p>\n\n\n\n<p>For a few years, I\u2019ve been producing all the material I need in markdown format. Markdown is a lightweight writing format that allows you to create documents simply and quickly, without worrying too much about formatting.<\/p>\n\n\n\n<p>This approach lets me write documentation faster and quickly extract slides from it using tools like Marp. Additionally, it\u2019s very easy to track differences between documentation versions and see what has changed over time.<\/p>\n\n\n\n<p>A few months ago, I found myself needing to translate a project\u2019s documentation into English. Doing this manually by copy-pasting text into an LLM and back again is tedious, time-consuming, and requires a lot of focus.<\/p>\n\n\n\n<p>I was about to write a program myself when I discovered extensions for GitHub that can automate documentation translation using simple Actions.

Instead, it\u2019s a tool that can help speed up work and improve code quality. Writing a prompt and expecting it to magically transform your thoughts into perfectly tailored code is unrealistic.<\/p>\n\n\n\n<p>Similarly, thinking that a single AI tool can solve all problems is a misconception, at least for now.<\/p>\n\n\n\n<p>The best way for a programmer to approach an LLM is to understand its limitations and identify the contexts where it can be used successfully. Start mentally cataloging these scenarios and associate each with a technique or tool that can be effectively employed.<\/p>\n\n\n\n<p>Likewise, it\u2019s unthinkable to encapsulate an entire project in a single prompt. It\u2019s much more effective to break the project into parts and ask the model to work on these individual components to achieve better, more precise results.<\/p>\n\n\n\n<p>Even in contexts where a model cannot generate code, it can likely document, comment, translate, or perform many other tasks that can speed up our work.<\/p>\n\n\n\n<p>We\u2019re not yet at a point where these tools can do everything automatically, but a programmer who knows how to use them can achieve excellent results and enhance the quality of their work.<\/p>\n\n\n\n<p>Improving your quality means becoming more effective and gradually shedding the \u201cjunior\u201d label to don the heavier and well-worn hat of a senior programmer.<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Artificial Intelligence ChatGPT and other AI tools have become essential for developers, but their true potential goes beyond answering prompts.
