<script src="startswith.js"></script>
Via npm:
npm install string.prototype.startswith
Then, in Node.js:
require('string.prototype.startswith');
// On Windows and on Mac systems with default settings, case doesn’t matter,
// which allows you to do this instead:
require('String.prototype.startsWith');

and String.prototype.contains
