Yes it says they are "rewriting the core in TypeScript", but that does not necessarily mean changing the code in any meaningful way. It means adding static types to the core itself, not only the interface (which DefinitivelyTyped is for).
- timneutkens 8y agoMax is definitely right here. We're not planning to deprecate or "completely rewrite" anything. We're not even "rewriting everything in Typescript at once". We're slowly converting files over one by one. No public APIs are changed. Furthermore, we have an extensive test suite of end-to-end tests for both development and production behavior.
