Do you know when to use TypeScript (vs JavaScript and CoffeeScript)?

Last updated by TiagoAraujo over 10 years ago.See history

TypeScript is the new flagship language from Microsoft that compiles into JavasScript.

  • Use JavaScript if you’re writing page specific script
  • Use jQuery to improve cross-browser support
  • Use TypeScript if you’re writing re-usable client side library

Don't use CoffeeScript (language is too different from JavaSript)

typescript good
Figure: Good - TypeScript is very similar to JavaScript so it’s easy to learn, and also helps developers learn proper JavaScript coding practices

typescript bad
Figure: Bad – CoffeeScript syntax is very different from JavaScript so it takes longer to learn
