Yes. And it depends.

If you are doing a small project with only one person, the benefits of Typescript might not be very apparent, and it would just seem like a lot of extra stuff you need to write.

If you are doing a large project with several people or more, then the benefits of Typescript would be very apparent. Since it eliminates a whole class of errors, and also makes the code self documenting.

Xingheng Wang what are those benefits? One thing I know is it gives type-checking (we can use flow for that)

Yes, Flow gives you some of the same benefits. As the name Typscript, Basically the key is type checking, and eliminate "most" errors resulting from type issues, and helps with documentation and team collaboration

Flow is like a smart linter (a checker), but Typescript is a more fully defined language and have a "compiler".

Both are invented to addressed the same problem, i.e. that Javascript lacked static type checking. They sometimes can catch errors the other one can miss. But seems Typescript is more popular because of the tooling.

But Pro and Cons of Flow vs Typescript is beyond the scope of the original question asked.
