Node.js

Node.js is a free open-source cross-platform JavaScript runtime environment.

To install node we can leverage brew:

Terminal

Node needs to be installed. After it's installed we can check the version which will show that it's installed:

Terminal

>

node -v

> Output:

v20.9.0

To create a simple node app we can we initialize it. If we create a new folder and navigate there in terminal then execute npm init which will prompt us some questions such as name of project then the folder will be a node app.

NPM is the node package manager which we will utilize very often to install packages. It's similar to yarn.
