Complete Guide to JavaScript in Atom

Detailed Guide to Writing JavaScript in Atom

Atom is one of the most well-known source code editors for JavaScript out there. It is free of cost, flexible, customizable, and is entirely built using HTML, CSS, JavaScript, and Node.js integration. 

As a beginner JS developer myself, I find Atom easy to understand, navigate and use. It allows you to write code efficiently. Furthermore, the most significant advantage is that its core is hackable. So if you want to add any features or functionalities, all you need to do is add another package.

How To Setup Atom For Writing JavaScript?

Before you begin to write and run a JavaScript program or script in Atom, you need two Atom packages:

  • Node.js atom package
  • the Script package on Atom

Installing Node.js

Node.js download page

Install Node.js on your system. This will enable you to write JavaScript code in your editor by providing access to JS commands and functionalities. Without it, you wouldn’t be able to write a JS program. You can download Node.js from the website

Node.js installer for MacOS

Once you have downloaded the Node.js installer, double-click it to install Node.js onto your computer.

Besides this, you need a series of packages and plugins that enhance the process of writing JS code and make it an efficient process. Following is the list of packages you need to install for writing JavaScript programs.

Yes, we can run JavaScript inside the Atom editor itself. All you need is to download and install the Script Package in Atom.
