A bug in the [slug] structure

[tutkun]

Instead of the following statement

val
    .replace(/ /g, '-')
    .replace(/[^\w-]+/g, '')
    .toLowerCase()

I think it makes more sense to use this:

  const nonLatin = [
    // non latin (from `f` to `t`):
    { f: /ä|ã|à|æ|â|Ä|Ã|À|Æ|Â/g, t: 'a' },
    { f: /ß/g, t: 'ss' },
    { f: /ş|Ş/g, t: 's' },
    { f: /ö|Ö/g, t: 'o' },
    { f: /ç|Ç/g, t: 'c' },
    { f: /ü|Ü/g, t: 'u' },
    { f: /ı|İ/g, t: 'i' },
    { f: /ğ|Ğ/g, t: 'g' },
    // special chars
    { f: /\s+/g, t: '-' }, // It replaces more than one consecutive space characters with a single "-" character
    { f: /[^\w-]+/g, t: '' },
    { f: /-{2,}/g, t: '-' }, // It replaces 2 or more "-" characters with a single "-" character.
  ]

  nonLatin.forEach(({ f, t }) => {
    val = val.replace(f, t)
  })

  return val.toLowerCase()
