WebAssembly JavaScript Engines

34 repos

Implementations and runtimes for executing JavaScript in WebAssembly environments, including interpreters, compilers, and virtual machines that bring JavaScript capabilities to the browser and beyond. The cluster covers core language features like garbage collection, function references, exception handling, threading, type systems, and promise integration — the essential components needed to run JavaScript reliably in WebAssembly contexts.
