To use npm (to install Sass), we first have to install Node.js, which we can easily do. Go to the official site and download the related installer (based on the operating system) or use your command line package managers like Homebrew or Chocolatey.

3. Install Sass
The –save-dev flag means that Sass is a development dependency (as you will see in your package.json, it is under the devDependecies object).
4. Set The Compile Commands
We can add any new script under the scripts object. Just remove the default one (named test) and add the following:
