Vanilla JavaScript Slugify + Accent removal - Just another JavaScript Slugifier with an extra line for Accent Removal

slugify.js

function slugify(text) {
  return text.toString().toLowerCase().trim()
	.normalize('NFD') 				 // separate accent from letter
	.replace(/[\u0300-\u036f]/g, '') // remove all separated accents
	.replace(/\s+/g, '-')            // replace spaces with -
	.replace(/&/g, '-and-')          // replace & with 'and'
	.replace(/[^\w\-]+/g, '')        // remove all non-word chars
	.replace(/--+/g, '-')            // replace multiple '-' with single '-'
}

Finally it made click and I believe to understand, what NFD does! Thank you very much for your efforts, @eek ! :-)
