An ES7 spec-compliant String.prototype.padRight shim. Invoke its "shim" method to shim String.prototype.padRight 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 padRight = require('string.prototype.padright');
assert(padRight('foo', 5, 'bar') === 'fooba');
padRight.shim();
assert(padRight('foo', 2) === 'foo'.padRight(2));
