Introduction
In this blog, you will see how to install Node.js and NPM on Windows.
Node.js
Node.js is a JavaScript runtime, which is built on
Chrome's V8 JavaScript engine. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient. Node.js' package ecosystem, npm, is the largest ecosystem of the open-source libraries in the world.
In software development, Node.js is an open-source, cross-platform runtime environment for developing Server-side Web Applications.
Although Node.js is not a JavaScript framework, many of its basic modules are written in JavaScript and the developers can write new modules in JavaScript.
Runtime is the code that runs our code. In Node.js or Chrome Browser, the runtime is written in C++ in a project called V8.
NPM
Node Package Manager (NPM) is used to install the packages that you want to use and provides a user interface to work with them.
