Similarly, object-oriented programming, one of the multiple programming paradigms that JavaScript supports, gives developers the flexibility to think more intuitively. This feature signifies looser restrictions around variable declarations. With it, you can have the advantages of an interpreted language like dynamic typing alongside the advantages of compiled code like stricter error prevention.ĭynamic typing is another feature of JavaScript. But the JIT compiler is a feature of the run-time interpreter. Interpreted languages are known for being slower than compiled languages.

JavaScript’s JIT compiler is especially noteworthy.

And most websites depend on JavaScript for their client-side behavior. Nearly every browser has an exclusive JavaScript engine to execute code. But with Node.js, a cross-platform runtime environment for JavaScript, code can be written and executed server-side. Initially, JavaScript could only be used on the client-side – that is, web browsers. JavaScript enables web pages to have complex content that may react, so to speak, to user manipulation or animate all by itself. Combined with HTML and CSS, JavaScript is one of the leading technologies used in the World Wide Web.īefore the development of JavaScript, the web was purely static.

JavaScript is a just-in-time (JIT) compiled, multi-paradigm programming language with dynamic typing.
