Set a function’s length.
Arguments: - `fn`: the function - `length`: the new length. Must be an integer between 0 and 2**32. - `loose`: Optional. If true, and the length fails to be set, do not throw. Default false.
Returns `fn`.
## Usage
```javascriptvar setFunctionLength = require('set-function-length');var assert = require('assert');
function zero() {}function one(_) {}function two(_, __) {}
assert.equal(zero.length, 0);assert.equal(one.length, 1);assert.equal(two.length, 2);
assert.equal(setFunctionLength(zero, 10), zero);assert.equal(setFunctionLength(one, 11), one);assert.equal(setFunctionLength(two, 12), two);
assert.equal(zero.length, 10);assert.equal(one.length, 11);assert.equal(two.length, 12);```
