TypeScript
JS with a typechecker that conquered the ecosystem — then a native Go compiler that made `tsc` an order of magnitude faster. The rare fad that became the floor.
Why TypeScript stuck
TypeScript stuck because large JS codebases collapse without schemas and IDE guardrails. It rode React's wave without fighting the runtime. TypeScript 7 ported the compiler to Go for ~10× full builds; framework tooling that needs the programmatic API stayed on 6.x until that surface existed. Even backend Node grew up and asked for types.
