Micro QuickJS is a new JavaScript engine by the famous Fabrice Bellard 🎉
📖 Written in C
🗜️ Uses 100 kB ROM
⚠️ Supports a subset of JS close to ES5
🐏 Runs programs in as little as 10 kB of RAM
🔥 Speed is comparable to the full QuickJS engine

What can you do with it? Well, it's just a REPL but doesn't bind to any useful host stuff yet, it's just a cool experiment :)

I rewrote Porffor's object implementation completely; it is now much faster and makes Wasm binaries 2-5x smaller than before when using objects!
Porffor's current worst benchmark gets 30% faster with >4x smaller Wasm; almost on par with QuickJS with only ~1 month of work!
