In respect to this, is CoffeeScript just JavaScript with syntactic sugar? The golden rule of CoffeeScript is: “It’s just JavaScript.” It basically says that CoffeeScript is just syntactic sugar on top of JavaScript, and for the most part this is accurate. However, CoffeeScript semantics are not exactly the same as JavaScript.
In addition, is CoffeeScript obsolete?
With the rise of ES6/7 and TypeScript, it seemed like CoffeeScript would become obsolete. But it’s not. CoffeeScript was one of the pioneers of the compile-to-JavaScript concept. In fact, some of things you now see in the modern JavaScript appeared in the first version of CoffeeScript some 8 years ago.
Also Know, is CoffeeScript hard to learn?
Yes, mostly. And that’s what makes CoffeeScript even more attractive. If you know JavaScript (and you probably would not be reading this if you did not), CoffeeScript doesn’t force you to learn new language semantics. In other words, you can do things the way you’re used to most of the time.
