This is honestly the first time I have looked close at CoffeeScript. At a passing glance, it looks really close to Python with javascript elements added in. Is that a correct assessment? If it is, this might be for me. My other question is: how nice does coffee script play with other libraries? We (unfortunately) use jQuery a lot. I have also been using underscore and lodash as well. Are those two even needed when wr…

If you like Python, you will love CoffeeScript. :) I have not used Underscore/Lodash in production, but I use jQuery a lot with CoffeeScript. CoffeeScript does not replace jQuery, although it can make your jQuery a lot nicer. As far as other libraries, there really are no restrictions; CoffeeScript compiles transparently to JavaScript. The only thing holding it back would be poor support in the specific ecosystem you…

I figured jQuery would be fine. Now that I think about it, I can't imagine why most things wouldn't really, since all javascript libraries are just extensions of those things. Does CoffeeScript just convert the modules methods/functions accordingly when needing to be called? Just curious how that works. Since so much of JavaScript development, especially nowadays, ties into a lot of frameworks/libraries (modules? I'm…

I like consistency. And I am paranoid. When I write JS, I always include semicolons. When I write CS, it is a non-issue.

CoffeeScript is still very relevant for me. I have two medium-sized Ember projects written in CoffeeScript (and Emblem and Sass--the original, indented variety, thank you very much). I have been looking at React (will probably skip due to the patent license) and Vue, but cannot imagine going back to semicolons and (excessive) curly braces and parens. If you married CoffeeScript just out of convenience (being able to…

I felt the same way when I switched from CoffeeScript to TypeScript but the type checking was worth all the braces, returns and lack of existential operator. If CoffeeScript added an (optional) type system I'd switch back in an instant.
