- 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
-
- ```javascript
- var 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);
