Discussion on: TypeScript is a waste of time. Change my mind.

This tone is better, and I appreciate that.

I work across multiple programming languages over years, and I think that every language has its own philosophy and its own way to achieve certain objectives (either it being the best is subjective).

Typescript is one language that I have to work with closely recently. While I appreciate some of the good things TS can bring to developers, I wouldn't say it is one-size-fit-all language for all the practical use cases.

In this particular discussion, I think a elaboration of how you can achieve "code as documentation" with inferred types in TS with some code example would be helpful. (Though I personally thing proper unit tests and JDoc would server better in this particular aspect, and it is not a TS specific thing).

I updated the original comment with examples. I don’t understand the “tone” comment though. If you’re reading my comments and assuming that I have some kind emotion behind them, then that’s a tone that you’re projecting onto it. My goal has always been to spread knowledge and enthusiasm.

As for the testing comment, every professional project I’ve developed recently has over 75% test coverage and it uses TypeScript. Why does everyone bring up testing vs types like they’re mutually exclusive? I like both. A lot.

I do not think testing and typing are "mutually exclusive". But one of the "pros" people keep pitching about Typescript is the "code as documentation" and "less error" talking point, which I think is already achieved by having proper unit tests whether the language is typed or not.

I could be biased here, but just talking about this specific "merit" Typescript can give is not convincing to me. It could be also due to working style, because I tend to write very thorough unit test coverage (~98% across the projects I developed in the past few years).
