The case for TypeScript

Everyone who starts TypeScript goes through the same arc: frustration → grudging acceptance → never going back.

What you actually get

1. Autocomplete that works — your editor knows the shape of every object
2. Refactoring confidence — rename a field and TypeScript shows every callsite that breaks
3. Documentation that can't lie — types are always in sync with the code

The friction is the point

When TypeScript complains, it's usually right. That error you're fighting is a bug you haven't written yet.

The best time to add TypeScript was at the start of the project. The second best time is now.
