One thing I really like about Typescript in strict mode is enforcement of handling null and undefined properly. Handling the stuff that usually isn't null is quite error prone as it typically works fine with well-formed data and only breaks once it encounters the real world with unexpected data.

Another very useful part is that refactoring becomes much easier, as you can simply follow the errors when you break an interface other parts of your code are relying on.

Typescript forces me to be more disciplined when coding, and that is clearly a good thing in my opinion. There are probably cases where you don't want that, e.g. rapid prototyping, but otherwise it's very useful.
