basic non-uuid uuid generator without going crazy!

not-uuid.js

// with map
[...Array(5)].map((elm, idx) => {
  switch(idx) {
    case 0:
       return Math.random().toString(36).slice(2, 8)
    case 4:
       return Math.random().toString(36).slice(2, 14)
    default:
       return Math.random().toString(36).slice(2, 6)
  }
}).join('-')

// with reduce
[...Array(5)].reduce((total, elm, idx) => {
  if (idx === 0) {
     total = Math.random().toString(36).slice(2, 8) + '-'
  } else if (idx === 4) {
     total += Math.random().toString(36).slice(2, 14)
  } else {
     total += Math.random().toString(36).slice(2, 6) + '-'
  }

 return total
}, '')

// returns "ahxiz7-xzec-xn2c-8di9-btlq6e3k9wg"
