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](https://github.com/es-shims/api) interface. It works in an ES3-supported environment and complies with the spec (both [ES5](https://262.ecma-international.org/5.1/#sec-15.5.4.20) and [current](https://tc39.es/ecma262/#sec-string.prototype.trim)).

Most common usage:

```js

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`
