How to slugify a string in JavaScript

A snippet of code I used to slugify a string

export function slugify(str) {  // Remove leading and trailing whitespace  str = str.trim()   // Make the string lowercase  str = str.toLowerCase()   // Remove accents, swap ñ for n, etc  str = str.normalize('NFD').replace(/[\u0300-\u036f]/g, '')   // Remove invalid characters  str = str.replace(/[^a-z0-9 -]/g, '')   // Replace whitespace with a hyphen  str = str.replace(/\s+/g, '-')   // Collapse consecutive hyphens  str = str.replace(/-+/g, '-')   return str }
