A Cartoon Intro to WebAssembly
summary
Explains why WebAssembly is actually faster: compact binary downloads, decoding is faster than JS parsing, and much compilation work moves ahead-of-time via LLVM and Clang so engines skip many JIT optimise/deopt cycles. Shows concrete limits: WebAssembly functions currently accept only numeric types and complex data lives in a module ArrayBuffer heap, with pointers passed as integers. Notes runtime realities: MVP ships in browsers today, cross-call trampolining causes nanosecond overhead, and threading, shared array buffers and GC integration are the next big items.
