Answer 4

TypeScript is a superset of JavaScript that brings users optional static types and solid tooling. Using TypeScript can help avoid painful bugs people commonly run into when writing JavaScript by type-checking your code. TypeScript can actually report issues without you even saving your file, and leverage the type system to help you write code even faster. This probably leads to a truly awesome editing experience, giving you time to think about and test the things that really matter.

Answer 6

typescript is extremely similar to js, to the point where is it basically js+type annotations and a few extra features for object oriented programming. you can use typescript everywhere you use js, but you need to transpile it to js first.

Answer 7

I'm just starting to play around with typescript and I really like it. There's a typescript playground to practice:

Answer 8

i would recommend it, since there are more js learning resoures available and switching over is very easy(and you will probably need js anyways if you want to do webdevelopment, even if you use mainly typescript)
