Tutorial 103: Installing Node on macOS

In this video, we are going to learn about node js, how to install it and use it.

What is Nodejs?
Node. js is a platform built on Chrome's JavaScript runtime for easily building fast and scalable network applications. Node. js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices. In simple language, it's a useful tool for helping us interpret our javaScript code. Before node javascript was only interpreted by browser but with node, javascript can run pretty much anywhere.
It's extremely powerful because it's blazingly fast, scalable, has a big, thriving community of developers behind it, a lot of prewritten code in its npm (basically an App Store for code).


A typical event is someone trying to access a port on the server


After installing the node on your device you are ready to run javascript file anywhere. To work with javascript open your terminal and type node, now the terminal is capable of interpreting javascript. Node. js is not a framework, it's only a runtime environment to run JavaScript on the server-side. Node. js, as a package, contains an interpreter and a compiler.
