A simple function for removing accents from Latin letters for producing URL parts, filenames, IDs, etc. It does not handle locale-specific transliterations (German umlauts, etc.), for which you’d need to reach for a more sophisticated library, such as slugify.

1. decompose accented characters into their base character
and combining diacritical mark.
2. remove combining diacritical marks
3. replace non-alphanumeric character sequences
with single dashes
4. remove trailing dashes

function slugify(str) {
return str
.normalize('NFD') // 1.
.replace(/[\u0300-\u036f]/g, '') // 2.
.replace(/[^a-z0-9]+/g, '-') // 3.
.replace(/(^\-)|(\-$)/g, ''); // 4.
