title: How to filter JSON object
body: <p>I have a JSON object that is a list of Students that have Name, FName, City, Class, Contact.
  Now I want to filter only the objects (Students) which belong to the specific city. Can I filter the mail json object</p>
  
  <pre><code>{

        "Name": "Student1",
        "FName": "FName1",
        "Class": "I",
        "City": "Delhi"
      },
      {
        "id": 2,
        "Name": "Student2",
        "FName": "FName2",
        "Class": "II",
        "City": "Mumbai"
      },
       {
        "id": 3,
