From a StackShare community member: "We are looking to rewrite our outdated front-end with TypeScript. Right now we have a mix of CoffeeScript and vanilla JavaScript. I have read that adopting TypeScript can help enforce better code quality, and best practices. I also heard good things about Flow (JS). Which one would you recommend and why?"

We originally (in 2017) started rewriting our platform from JavaScript to Flow (JS) but found the library support for Flow was lacking. After switching gears to TypeScript we've never looked back. At this point we're finding that frontend and backend libraries are supporting TypeScript out of the box and where the support is missing that the commuity is typically got a solution in hand.

I use TypeScript because:

  • incredible developer tooling and community support
  • actively developed and supported by Microsoft (yes, I like Microsoft) ;)
  • easier to make sense of a TS codebase because the annotations provide so much more context than plain JS
  • refactors become easier (VSCode has superb support for TS)

I've switched back and forth between TS and Flow and decided a year ago to abandon Flow completely in favor of TS. I don't want to bash Flow, however, my main grievances are very poor tooling (editor integration leaves much to be desired), a slower release cycle, and subpar docs and community support.
