I have mixed feelings about Typescript, I hate reading code with heavy TS annotations because JS formatters are designed to keep line widths short, so you end up with a confusing mess of line breaks. Pure JS is also just more readable.

Also you can so easily go overboard with TS and design all sorts of crazy types and abstractions based on those types that become a net negative in your codebase.

However it does feel really damn nice to have it catch errors and give you great autocomplete and refactoring tooling.
