Slugify string

When you generate URLs from titles, the title typically can't be used directly — spaces, question marks and other special characters don't belong in URL slugs. That's where a slugify function comes in handy.

This is the function I like to use:

const slugify = (str) => {
	return str
		.normalize("NFD")
		.replace(/[̀-ͯ]/g, "")
		.toLowerCase()
		.trim()
		.replace(/\s+/g, "-")
		.replace(/[^\w\-]+/g, "")
		.replace(/\-\-+/g, "-")
}

It does some cool stuff. Go ahead and test it out here:
