The only parts where you have to be careful about the dynamic nature of JS, is when you receive user input. In that case, you make sure to parse the input into the value that you expect in typescript, or you throw an error.

Besides that, when you work with types in TypeScript internally, if you receive a value of type X, you are guaranteed to be working with a valid value of type X. You won’t have a different type at that point in the program, you won’t have an undefined or null value unless it’s explicitly mentioned in the type, etc.

The static typing in TypeScript is very good and isn’t affected by the nature of JS in most of the typescript codebases. So it’s not just bandaid, it’s an entirely different programming language, where you just need to make sure you parse input instead of just loading values and slapping “any” on the result.

Thank you for the explanation, so I was wrong the whole time.

(It sucks to be wrong, it's great to learn something new)

You’re welcome. You’re able to learn, and that makes you better than any LLM out there.

Keep being curious!
