title: Javascript random ordering with seed
body: <p>I want to randomly shuffle a list of 4 items but with a seed so that so long as you have the same seed the you will get the same order of items.</p>
  
  <pre><code>["a", "b", "c", "d"]
  </code></pre>
  
  <p>I figure I can get the seed with Math.random, I don't need something very exact. How do I sort according to the seed?</p>
