String.prototype.trim

![npm badge][npm-badge-png]

An ES5 spec-compliant String.prototype.trim shim. Invoke its "shim" method to shim String.prototype.trim if it is unavailable.

This package implements the es-shim API interface. It works in an ES3-supported environment and complies with the spec (both ES5 and current).

Most common usage:

var assert = require('assert');
var trim = require('string.prototype.trim');

assert(trim(' \t\na \t\n') === 'a');

trim.shim(); // will be a no-op if not needed

assert(trim(' \t\na \t\n') === ' \t\na \t\n'.trim());

Engine Bugs

Some implementations of String#trim incorrectly trim zero-width spaces. This shim detects and corrects this behavior.

Tests

Simply clone the repo, npm install, and run npm test
