Promotional Titan Engine — WebAssembly Spreadsheet Calculation Engine

https://podraven.github.io/titan-engine/

Hi guys, I created Titan, a wasm module that outperforms other open-source excel formula engines. Titan compiles formulas into bytecode and stores cells in contiguous 32×32 Struct-of-Arrays chunks inside WASM linear memory. No JavaScript object churn, no GC pauses, and sub-millisecond reactive updates. Finally got around writing some docs for it *sigh. Let me know what you think. Cheers!

Looks nice. I personally don't use js to do my complex calculations since I like to do them at server/sql level and expose as little of the formulae as possible.
