A robust & optimized ES3-compatible polyfill for [the `RegExp.escape` proposal](https://github.com/tc39/proposal-regex-escaping).
Use it to safely escape RegExp special tokens for use in `new RegExp`.
Use it as a standalone function, or call its `shim` method to install it as a polyfill.
## Example
```js
var escape = require('regexp.escape');
var assert = require('assert');
var str = 'hello. how are you?';
var regex = new RegExp('^' + escape(str) + '$');
assert.match(str, regex);
assert.doesNotMatch('hello, how are you!', regex);
```
## Tests
Simply clone the repo, `npm install`, and run `npm test`
