What is Sass in JavaScript?

The sass package on npm is a pure-JavaScript package built from the Dart Sass implementation . In addition to Dart Sass’s command-line interface, it provides a JavaScript API that can be used to drive Sass compilations from JavaScript.

For the most part, no you don’t need Sass to get work done . The internet has been around for a long time and CSS was here WAY before Sass and people were able to get work done.

Sass is an extension of CSS3 , adding nested rules, variables, mixins, selector inheritance, and more. It’s translated to well-formatted, standard CSS using the command line tool or a web-framework plugin. So Sass is a great way of writing a more terse and functional way of writing CSS.
