An ES2019-spec-compliant `String.prototype.trimLeft` shim. Invoke its "shim" method to shim `String.prototype.trimLeft` 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 trimLeft = require('string.prototype.trimleft');

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

if (!String.prototype.trimLeft) {

	trimLeft.shim();

}

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

```

## Tests

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