But despite its nearly 3-decade-long journey, developers still have a love-hate relationship with this language. Some say it is not even a proper programming language, while others swear by it.
There are experienced JS developers who argue that all it needs is a better understanding of its logic and most of the limitations have been overcome by IDE.
The challenge, though, is to grow into an expert JS developer which needs knowledge of more than just the basics.
- Best for front-end development
- How to bootstrap Node.js with Express
- Use a document database
- Weak-typing and aggressive type coercion
If your code is even slightly incorrect in this weak-typing language, you could end up getting a completely illogical output thanks to its aggressive coercion.
- Lack of security on the client-side
A threat actor could even place some code into the original code that can cause a data breach on the website/ app. This compromises the security of the application on the client side.
- Poor browser support
- Lack of debugging
But when you think of alternatives, be it back-end or front-end, it is important to remember that every programming language or tool has its own limitations. So what you choose will depend on your development purpose. You have to be clear about what you need and what you can do without.
Some of the most popular compilers that expert developers suggest are:
- Haxe, and more
Only you can decide which alternative to choose because the choice ultimately depends on one thing – the purpose. Depending on what you are aiming to achieve.
If you are looking for an alternative for back-end development the most viable options could be Python, Ruby, Kotlin or PHP, for instance. If your purpose is front-end development, TypeScript, CoffeeScript, Elm, ClojureScript or Dart could be the better alternatives.
You need to first identify your needs, and then carry out your own research to see which of these options best meet your demands.
Most users find coding with TypeScript robust and less error-prone, but they also think it can be quite clumsy and complex.
Kotlin is another back-end programming language that gives better readability and requires writing fewer codes. It was developed by the industry and not the academia, which is why Kotlin focuses more on the practical problems faced by developers in the field. It is more popular because of its capability of multiplatform programming. For instance, it can share code between Android and iOS systems in mobile app development.
Ruby is a robust, dynamically-typed and object-oriented programming language with a very simple syntax, that’s quite close to the English language. It may be a little slower than Python, but is still one of the most popular alternatives.
PHP is being called the future of back-end development because of its flexible and flawless features. The syntax in this language is very expressive, which gives you some creative freedom. PHP has inbuilt website development capabilities too. It has built-in security features to keep websites safe against threats.
- React Native
Apart from the options for front-end and back-end development already mentioned above, you may also want to check out the following alternatives for web applications.
Elm is a new language built for functional programming, with reactive programming at its core. The advanced type system in this language ensures zero run-time errors in production codes and the better HTML rendering performances allow clean front-end architecture for the web.
- The CoffeeScript syntax is relatively easier and simpler making it more manageable for larger projects.
- ClojureScript has a much simpler syntax because of the Lisp-ness which makes it easier to comprehend.
- There are no run-time exceptions in Elm that allows building large front-end codebases without testing at once.
