1Keys: How I Made a Piano in Only 1KB of JavaScript — A month ago we promoted JS1024, a contest to build the coolest thing possible in just 1024 bytes of JavaScript.

If this genius seems familiar, he also did a writeup about implementing a 3D racing game in 2KB of JavaScript recently, and more besides.

GPU.js: GPU Accelerated JavaScript — It’s been a while since we linked to this project but it continues to get frequent updates. It’s compiles JavaScript functions into shader language so they can run on GPUs (via WebGL or HeadlessGL). This has a lot of use cases (and there are plenty of demos here) but if you need to do lots of math in parallel.. you need to check this out.
