Elevator pitch (30 s)

SuperJS is a strict, sound superset of JavaScript — not TypeScript with a new extension. It bans any, intersection types, and conditional types; adds sum types, exhaustive match, and default null safety. One hand-written compiler ships today as clean ES2022; native and WASM targets are on the roadmap.

Key numbers (2026-06-24 bench)

Cold compile ~14k LOC: 81 ms (vs tsc typecheck ~721 ms on same corpus)
LSP idle heap @ ~140k LOC: 196 MB (target ≤ 250 MB)
30 @superjs/types-* wrappers for npm interop
