Is CoffeeScript the same as JavaScript?

CoffeeScript is a little language that compiles into JavaScript. CoffeeScript is an attempt to expose the good parts of JavaScript in a simple way. The golden rule of CoffeeScript is: “It’s just JavaScript.” The code compiles one-to-one into the equivalent JS, and there is no interpretation at runtime.

How do I run a CoffeeScript file?

There are two ways to run CoffeeScript in WebStorm:

Is CoffeeScript more performant than written code?

Due to optimizations CoffeeScript uses, when it’s compiled down, the resulting JavaScript is just as performant or in some instances it’s even more performant over hand-written code. You can learn a lot about JavaScript by looking at the JavaScript that CoffeeScript compiles down to.

How to compile CoffeeScript from the command line?

Compile and print a little snippet of CoffeeScript directly from the command line. For example: require () the given module before starting the REPL or evaluating the code given with the –eval flag. Compile the JavaScript without the top-level function safety wrapper. Suppress the “Generated by CoffeeScript” header.
