| 4 | * Syntactic sugar for invoking a function and expanding an array for arguments.
|
|---|
| 5 | *
|
|---|
| 6 | * Common use case would be to use `Function.prototype.apply`.
|
|---|
| 7 | *
|
|---|
| 8 | * ```js
|
|---|
| 9 | * function f(x, y, z) {}
|
|---|
| 10 | * var args = [1, 2, 3];
|
|---|
| 11 | * f.apply(null, args);
|
|---|
| 12 | * ```
|
|---|
| 13 | *
|
|---|
| 14 | * With `spread` this example can be re-written.
|
|---|
| 15 | *
|
|---|
| 16 | * ```js
|
|---|
| 17 | * spread(function(x, y, z) {})([1, 2, 3]);
|
|---|
| 18 | * ```
|
|---|
| 19 | *
|
|---|
| 20 | * @param {Function} callback
|
|---|
| 21 | *
|
|---|
| 22 | * @returns {Function}
