Function.prototype.apply 's handling of an object instead of an array. It forces the object through Array.prototype.slice function as 'this' to create an array, pretty much what we do to turn an arguments object into a real array.
Array.apply(null, [1, 2, 3])
> [1, 2, 3]
Array.apply(null, [1, 2, 3]).length
> 3
Array.apply(null, {length:3})
> [undefined, undefined, undefined]
Array.apply(null, {length:3}).length

Here are some things you can do with Gists in GistBox.
// Use Gists to store code you would like to remember later on
console.log(window); // log the "window" object to the console

onlyWhen - run a function with its original arguments once a condition is met.
/**
* Creates a wrapped version of a funtion that will run with the original
* arguments, once a condition is met. If the condition is not met, it will
* be checked on a set interval until it is met.
*
* @param {Boolean} condition function you expect to eventually return a truthy value
* @param {Function} func original function to resolve
* @param {Number} interval time to wait between checks
* @return {Function} wrapped function you call can call as it it was the original function

Standalone getScript. This performs the same ability as jQuery.getScript, including the optional callback, but doesn't support the Promises implementation shared with all the other jQuery.ajax methods.

Grunt task for cycling through each item in a directory on an interval and creating a symlink which points to it. This is helpful for cycling through logs, or an archive of data captured over time. Coupled with a server, it serves as a good simulated data endpoint. This should be defined after grunt.initConfig inside your Gruntfile, or you can r…
