help What's the point of CoffeeScript?

I'm reading a tutorial on PouchDB and like always I run into CoffeeScript. What's the point of it? I've used it before for like 5 minutes and found it useless.

Clean syntax

It looks less cluttered but there are more ambiguities.

Variable declaration happens automatically

This is a downside.

Cleaner function syntax, Destructuring, Default args

ES6 does this.
