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);

assert.equal(zero.length, 10); assert.equal(one.length, 11); assert.equal(two.length, 12); ```
