Description

The JS-compiled version of Dart Sass hovers around 2.5x and 3x slower than when running on the Dart VM. Some slowdown is inevitable, but this seems extreme. We should put dedicated effort into profiling the JS output and optimizing hot spots.

Contributor guide

Research direction
Profile the JavaScript compiled output using browser DevTools or Node.js profiling tools to identify hot spots. Focus on functions with high execution time. Compare with Dart VM performance to understand overhead.
