An ES2017 spec-compliant `String.prototype.padStart` shim. Invoke its "shim" method to shim `String.prototype.padStart` 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](https://github.com/tc39/ecma262/pull/581).

Most common usage:
```js
var padStart = require('string.prototype.padstart');

assert(padStart('foo', 5, 'bar') === 'bafoo');

padStart.shim();

assert(padStart('foo', 2) === 'foo'.padStart(2));
```

## Tests
Simply clone the repo, `npm install`, and run `npm test`
