/** |
|
* 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} |
|
