CoffeeScript directly compiles into JavaScript. The fact that the source code is written in CS does not mean you can't use it with JS.

By comparison, think about Python. Some libraries use C for performance gain. Does that mean you can't use them with Python? No. These are still perfectly valid Python libraries.

That's a terrible argument. I still write and read Python with libraries that use C (for example: the entire standard library). If you want an example that fits the point you are trying to make, consider Lua/C, where you _can_ mix the two easily.

The point is still flawed, though - CoffeeScript is not JavaScript, and I have no interest in learning it (I'd rather spend the time learning to write better JS myself). I, and everyone else with my mindset, has their time wasted by this mislabelling; we would not have clicked through if the title said CoffeeScript.

But who said you had to use CoffeeScript? You can perfectly use this library by writing standard javascript.

The author decided to write the source code of the library in CoffeeScript, which then compiles to perfectly valid javascript that you can import.

The analogy about Python is that you don't have to know C to be able to use a Python library written in C..
