Difference between JavaScript and Node.js ![]() In Node.js everything is a module and using these modules developers make use of Node.js in creating web APIs, Rest API servers, command-line applications, and real-time chat applications. The nicest part about Node.js is that it never blocks I/O, is event-driven, and can be used to create highly scalable apps. Node.js was first introduced in 2009 developed by Ryan Dahl and is a runtime environment for JavaScript built on Google’s v8 engine whose main purpose is to run JavaScript on the server and hence JavaScript can be executed outside of the browser. JavaScript is an Object-oriented programming language that can be used on the client-side as well as on the server-side and developers not only use it for creating web pages but also it is used for game development and mobile app development. As discussed earlier, JavaScript is a high-level programming language that has all the functionalities normally a programming language has. JavaScript’s first version was launched in 1995 and it was developed by Brendan Eich of Netscape (then called LiveScript). In this post, we will walk you through what JavaScript and Node.js are, and then we will demonstrate the differences between JavaScript and Node.js. JavaScript is a lightweight (easy to learn syntax) and object-oriented programming language whereas Node.js is a runtime environment built on google v8 engine and typically used to represent a list of objects and functions that JavaScript programs can access. JavaScript is a high-level programming language that makes our web pages and web applications dynamic and interactive by giving them the ability to think and act.
