And that's fine, but once you see the drastic difference in readability I think it's fair to say you will want to use CoffeeScript for its readability.
Here's this example:
Okay, but doesn't all the interpretation of the more readable code make running code on CoffeeScript slower?
No, luckily for us CoffeScript code is compiled to a JS file before it's interpreted using JIT.
So why haven't I seen anything using CoffeScript? or at least heard about it?
So, should I use TypeScript?
If you want sure, but code is meant to be readable for time efficiency purposes and TypeScript doesn't meet that goal, in fact it's even less readable than Vanilla JS in my opinion.
Are you going to go get it or what?
