liberate is a function that turns a method operating on a
this value into a function explicitly taking that value as its first argument.
Yep! It's actually insanely useful in many circumstances.
Did you know that the non-mutating array methods actually work on any array-like? It's true! Many people are accustomed to using them like this:
// Get the arguments to this function except the first. Array.prototype.slice.call(arguments, 1)
But ew, what's with that
call junk? Why can't I just call it like a normal function? Well, you can:
var liberate = require('liberate') , slice = liberate(Array.prototype.slice) slice(arguments, 1)
You still have to reference
Array.prototype.slice, but you do it once and then you can slice as many things as you want without the verbosity.
liberate is legitimately useful. Why not make a module of it?
While you're busy repeating yourself, I'll be busy actually coding.
It's not? Oh well. Use the module or don't. It's up to you.
Why am I arguing with myself anyway?
Ripped straight from sinful.js, as I found it useful on its own.
