Building Web Servers and Server Applications Node.js is also lightweight enough to serve as a scalable tool for microservices, allowing you to develop a single app comprising small services with individual processes. Node.js can reduce server response time due to its single-threaded nature and non-blocking architecture and omit delays. The implementation of JavaScript code in Node.js also plays an important role in web development. Meanwhile, mobile application development frameworks such as Cordova and Titanium make it possible to create native or hybrid applications. They allow developers to reuse and update code components without affecting each other, function or value-wise. It saves them time and effort from having to code programming features from scratch.Įach JavaScript framework has features that aim to simplify the development and debugging process.įor example, front-end JavaScript frameworks like jQuery and ReactJS improve design efficiency. The development of JavaScript frameworks, consisting of JavaScript code libraries, allows developers to use pre-written JavaScript code in their projects. The following are several basic uses of JavaScript.

While it caters to web-based programs the most, JavaScript programming features have other implementations in different areas. Originally run on the client-side, the JavaScript implementation has branched out to the server-side after the Node.js development ‒ a cross-platform server environment built on the Google Chrome JavaScript V8 engine.

Today, JavaScript has plenty of frameworks and libraries to simplify complex projects, such as AngularJS, jQuery, and ReactJS. The latter even started developing the first modern JavaScript engine, called V8, which compiles bytecode into native machine code. JavaScript has continued to grow alongside new browsers like Mozilla Firefox and Google Chrome since then. It was a general-purpose scripting language to ensure web pages’ interoperability across different browsers and devices.

After Netscape submitted it to ECMA International as a standard specification for web browsers, JavaScript pioneered the release of ECMAScript.

The initial versions of the scripting language were for internal use only.
