What’s inside WebAssembly
summary
Builds a working cellular automaton in wasm text format that compiles to a binary, exposes memory and globals to JavaScript, and renders evolving rows in the browser; implements index, load/store, bit-shift packing of three neighbor bits, an eight-entry function table for rules, and an evolve loop that actually runs. Demos include small grids (row size 5), larger runs (115), shows Rule 30 chaotic behavior and notes WebAssembly Studio + AssemblyScript for compiling and debugging, and confirms the code works in-browser.
