What is TS Migrate?

ts-migrate analyses your JavaScript files, infers types from usage patterns, and rewrites them as TypeScript with accurate annotations. It handles JSDoc-to-type conversion, adds strict null checks incrementally, and generates a migration report with files ordered by difficulty so you tackle them in the right sequence.
