Simple JavaScript slugify

Daniel WertheimDaniel Wertheim

I confess. Me and regular expressions aren’t buddy, buddies. So it took some trial and error before reaching this point with something useful in the context of generating slugs. There are probably tons of scripts like these, but here we go.

if (!String.prototype.toSlug) {  
  String.prototype.toSlug = function () {
    return this.toLowerCase()
      .replace(/s/g, '-')
      .replace(/&/g, 'and')

With this we can now get something that looks like slugs.

console.log("Some  text".toSlug());  
=> some-text

=> sometext

console.log("Some----text & some 123".toSlug());  
=> some-text-and-some-123

Covers my needs. Feel free to drop comments about good improvements.
