I understand why some teams use plain JavaScript
I understand why some teams use plain JavaScript.
Perhaps the code is simple and rarely changes.
Perhaps the team is small, so types feel like overkill.
Perhaps they're not familiar with TypeScript or the benefits of types.
But I don't understand why a team already using TS, with a robust set of types, and a public API would delete all the types and switch back to JS.
That makes no sense to me.
