> mypy is the static type checker that is the most popular (28.3k repositories, 1.9k packages), if you are using other type checkers then congrats, you will just be the CoffeeScript/Reason user of the JS world, refusing to believe that TypeScript won the mindshare
Not really. TypeScript is a JS superset (and TypeScript tooling works with unadorned JS, too), but Coffee script/Reason are incompatible languages that happen to compile to JS and have static typing. All of the Python typecheckers are more like TypeScript, except that even the type annotations and much of the type system is also standardized as part of the core language. You can literally use any of them on the same code base, and get largely the same results (some will catch some type errors that others miss, some will flag some correct code as possibly erroneous that others would leave alone, but the differences tend to be minor.)
