I'm still in the 'feels good' stage with meticulously modelling the types of data I use in Angular with Typescript. Initially, I couldn't really see the point, but if anything I find it helps with catching errors and response expectations before build-time and also auto-completion/pseudo-documentation/hinting in VSCode. Now, I love it.
