An ES2019-spec-compliant `String.prototype.trimStart` shim. Invoke its "shim" method to shim `String.prototype.trimStart` 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://www.ecma-international.org/ecma-262/6.0/#sec-object.assign). In an ES6 environment, it will also work properly with `Symbol`s.

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

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

if (!String.prototype.trimStart) {
	trimStart.shim();
}

assert(trimStart(' \t\na \t\n') === ' \t\na \t\n'.trimStart());
```

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