I freaking LOVE Typescript. I shipped an app about 90 days ago based on Typescript. https://getpolarized.io/ https://getpolarized.io/ It's basically a document manager which supports annotations, comments and keeping your documents in the cloud. Typescript was a MASSIVE win. If you're on a simple code base doing a refactor is easy. Anything significant and it's a nightmare. If you change an object method JS won't complain. With Typescript and IntelliJ or VS Code it's just a simple refactoring and your code just works. I would have probably given up on the project had it not been for TS.
