Like any other application, you can find it by going into Finder, navigating to the Applications folder, and then into the Utilities folder. To access the command line interface, you’ll use the Terminal application provided by macOS. The command line, also known as a shell, lets you automate many tasks you do on your computer daily, and is an essential tool for software developers. Instead of clicking buttons with your mouse, you’ll type commands as text and receive text-based feedback.

The command line is a non-graphical way to interact with your computer. You’ll use the command line to install Node.js and run various commands related to developing Node.js applications. You will need a macOS computer running High Sierra or higher with administrative access and an internet connection. In this tutorial, you’ll set up a Node.js programming environment on your local macOS machine using Homebrew, and you’ll test your environment out by writing a simple Node.js program. It’s also the runtime that powers many client-side development tools for modern JavaScript frameworks. Node.js is an open source JavaScript runtime environment for easily building server-side applications.
