Choosing the right back-end technology is a crucial task in the planning stage of a software or app development. The back-end technology will define both the development cost and the subsequent maintenance costs. It will also determine how scalable the software or app is and how fast it can be deployed to the end users.
Node.JS is a back-end technology platform that powers JS scripts to run outside browsers. Node.Js is released under the MIT (Massachusetts Institute of Technology) license that allows the use of Node.Js free for commercial purposes as well. JavaScript can be termed the most popular client-side programming language, and together with the JavaScript framework, Node.Js is in high demand. This has led to numerous giants using Node.Js which includes Netflix, IBM, Microsoft, and PayPal.
What Is NodeJS And How Different It Is From JavaScript?
NodeJS is an open-source, cross-platform JavaScript runtime environment that allows developers to build server-side applications using JavaScript. It is built on top of Google's V8 engine, which is the same engine used by the Google Chrome browser to execute JavaScript code.
JavaScript, on the other hand, is a programming language that is used primarily for building web applications. It is mainly used in the browser to add interactivity and dynamic behavior to web pages.
The main difference between NodeJS and JavaScript is that NodeJS is a server-side runtime environment that allows developers to write JavaScript code outside of the browser, while JavaScript is a client-side scripting language that is primarily used in the browser.
NodeJS allows developers to write server-side code using JavaScript, which means that developers can use the same language for both client-side and server-side development, making it easier to build full-stack web applications.
In summary, NodeJS is a server-side JavaScript runtime environment that allows developers to build server-side applications using JavaScript, while JavaScript is a client-side scripting language that is primarily used in the browser to add interactivity and dynamic behavior to web pages.
