title: GatsbyJS: How to store an array in a markdown file?
body: <p>Suppose I have the following index.md in my Gatsby app:</p>
  
  <pre><code>---
  title: "Names"
  numberOfNames: "3"
  ---
  </code></pre>
  
  <p>Now I would like to add an array of separate names like "Alex", "Bill", "Jack" under "names" tag.</p>
  
  <p>How would I represent that array in a markdown file so that later I could iterate over it in my .js file?</p>
