String.prototype.padLeft

An ES7 spec-compliant String.prototype.padLeft shim. Invoke its "shim" method to shim String.prototype.padLeft if it is unavailable.

This package implements the es-shim API interface. It works in an ES3-supported environment and complies with the spec proposal.

Most common usage:

var padLeft = require('string.prototype.padleft');

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

padLeft.shim();

assert(padLeft('foo', 2)) === 'foo'.padLeft(2));
