Io just pivoted to WebAssembly. One WASI binary runs everywhere, plus a browser REPL with a bidirectional Io JavaScript bridge. Still early-stage; expect sharp edges. Legacy native build preserved on the native branch. github.com/IoLanguage/io

Io 2026.03.06-stackless-alpha: Eval loop now runs on heap-allocated frames instead of C stack recursion. This enables portable coroutines and first-class continuations without platform-specific assembly, setjmp/longjmp or ucontext. github.com/IoLanguage/io

@blu_blood_hero @Nikso Nice! Does this implementation support coroutines? Is the Io stack separated from the JS stack?

This version supports an emscripten fibers implementation of coroutines. Would like to add a transparent Io/JS bridge, and examples of using coros to eliminate JS callback hell when time permits.

Experimental online Io REPL is up: iolanguage.org/repl/ Exmscripten was used to compile Io to WASM. Works on desktop, but there's bug on mobile browsers I haven't figured out yet. Any ideas?

@Karlos_Georgy “ary2d flatten sum” would be more terse and avoid a mutating pop operation

@gavr123456789 It was a bit of a trick question. JSON is valid for the Io parser. It only needs to be pulled from the AST, which can be done is several ways.
