Sass parser in JavaScript. Have a look at the Interactive Playground to play around with compiling SCSS to CSS in your browser.
This is a convenience API for emscripted libsass (at v3.4.9). If you're looking to run Sass in node, you're probably looking for node-sass. Sass.js and node-sass should generate the same results.
The total size of gzipped content is ~600KB (~2KB sass.js, ~80KB sass.worker.js, ~520KB libsass.wasm). Without gzip it's ~6KB sass.js, ~360KB sass.worker.js, ~1.7MB libsass.wasm.
If you're on NodeJS, please use the (considerably faster) node-sass instead. You may also be interested in giving Dart Sass a shot.
