/**
|
|
* Syntactic sugar for invoking a function and expanding an array for arguments.
|
|
*
|
|
* Common use case would be to use `Function.prototype.apply`.
|
|
*
|
|
* ```js
|
|
* function f(x, y, z) {}
|
|
* var args = [1, 2, 3];
|
|
* f.apply(null, args);
|
|
* ```
|
|
*
|
|
* With `spread` this example can be re-written.
|
|
*
|
|
* ```js
|
|
* spread(function(x, y, z) {})([1, 2, 3]);
|
|
* ```
|
|
*
|
|
* @param {Function} callback
|
|
* @returns {Function}
|
