title: How to correctly set up a object in JSON in JavaScript?
body: <p>I want to map a key "coordinate" to an object with two key-value pairs which are a key of "latitude" mapping to the integer 50 and a key "longitude" mapping to the integer 60.</p>
  
  <pre><code>"coordinate" : [{
      "latitude": 50, "longitude": 60
  }]
  </code></pre>
  
  <p>My question is this the correct way to set up an object in JSON in JavaScript because I keep getting error or typo at "coordinate"?</p>
