title: Find in which polygon certain coordinate (latitude, longitude) lies with MongoDB?
body: <p>Let's say 100 documents (so to say polygons) in a collection named <strong>Areas</strong> with this structure:</p>
  
  <pre class="lang-js prettyprint-override"><code>{
    ...otherFields,
    commonName: "Butwal",
    area: {
      type: "Polygon",
      coordinates: [
        {
          latitude: 27.66779856,
          longitude: 83.4668095
        },
        ...
        ...
        {
          latitude: 27.66779856,
          longitude: "83.4668095
        }
      ]
    }
  }
  </code></pre>
  
  <p>Now I would like to find in which of those document(so to say polygon) this coordinate lies:</p>
  
  <pre class="lang-js prettyprint-override"><code>{
    latitude: 27.683793,
    longitude: 83.458689
  }
  </code></pre>
  
  <p><strong>with the help of MongoDB either aggregation or other operators please help!!</strong></p>
  
  <p><strong>OR if I can do with javascript(NodeJS) in very performance way</strong></p>
  
  <p><strong>OR with some google maps API</strong></p>
