What are the reasons for its success?
Historically, there have been three programming languages that you can render in a web browser:
- HTML, which is responsible for the structure of the web page.
- CSS, which is responsible for how the web page looks.
Advantages and disadvantages
Like all programming languages, JS has certain advantages and disadvantages in contrast to other programming languages.
- Dynamic typing. This is very beneficial for creating prototypes quickly, but static typing could be more useful in large scale projects due to the type safety and transparency it provides.
We’ll list a couple of them:
As its strengths, Angular lists speed, performance, and well-developed tooling. What is more, Angular has a ton of built-in features–whatever you need for your daily web development, Angular is likely to have it.
In addition, you can use Angular to build web and native mobile and desktop apps.
React is a web app framework whose development is led by Facebook. In contrast to Angular, it is much more minimalistic. Therefore, if you need some additional stuff that the framework doesn’t include, you frequently have to search for community-made libraries.
Like Angular, it enables you to make mobile apps with React Native.
You can think of Vue as being somewhere in the middle of React and Angular in the number of provided features. In contrast to both of them, Vue was not made by a large company like Google or Facebook. Instead, it is developed and maintained purely by the open-source community.
Deno, in contrast, is much newer and less battle-tested. But according to the creator of Deno, Ryan Dahl (who is also the creator of Node.js), it improves security, TypeScript support, and other Node’s features.
Like Node, it also uses V8. It’s built in Rust.
Here are the most popular ones:
There’s also WebAssembly, but we will delve into the exact details of it below.
Any other server-side programming language like Java, Python, or Ruby can serve as an alternative for JS on the backend. JS shows similar performance and has the benefit of having the same language on the client and server sides.
A particular innovation in the web browser space is WebAssembly (or WASM in short).
WebAssembly is a portable compilation target that can enable one to compile any programming language to code that runs in the browser. In other words, it lets you write web apps in any language.
