Hey! Also JavaScript

function diamond(n){
  if (n <= 0 || n % 2 === 0) {
    return null;
  }

  const repeater = ch => n => ch.repeat(n)
  const spacer = repeater(' ')
  const asterixer = repeater('*')

  let diam = ''
  for (let row = 1; row <= n; row++) {
    const spaces = Math.abs(n - ((2*row) - 1))
    const stars = n - spaces
    diam += `${spacer(spaces / 2)}${asterixer(stars)}\n`
  }

  return diam
}

This is my favorite JS answer to this challenge 👍 I like how you used the repeater, keeps things clean & compact.
