Description
TypeScript 6.0 is the last release built on JavaScript — and the bridge to TypeScript 7.0, which is being rewritten in Go for native speed and parallel type-checking. This release modernizes defaults (strict mode on, ESM-first, ES2025 target), adds built-in Temporal API types, Map.getOrInsert, and RegExp.escape, and deprecates legacy patterns that won't survive the native port. If you write TypeScript, the migration window to the native era starts now.

Could you build this?
No TypeScript is one of the world's most complex programming language compilers and type checkers, maintained by a dedicated team of language and compiler engineers.
What it would actually take: Requires deep computer science expertise in compiler architecture, abstract syntax trees (AST), flow-sensitive type analysis, inference engines, and language specification compliance. Building TypeScript requires writing parsers, type checkers, and emitter engines capable of processing millions of lines of code deterministically.
