TypeScript is supposed to make your development life easier, but I vividly recall my earliest memories of TypeScript involving a lot of cursing, confusion about errors, and wondering why anyone would ever waste time writing out all types. I used to write type definitions for hours and complain that I definitely didn't feel my productivity getting any better. Today, I love TypeScript and usually find projects written in plain old JavaScript to be injurious to my mental health.
