title: how to update specific value in json array
body: <p>New to manipulating JSON, I appreciate the help! This project uses VueJs 2 if that makes a difference.</p>
  
  <p>I am trying to update a key value, in this example it is "group" for a specific applicant identified by the ID.</p>
  
  <p>I am trying to accomplish something along of lines of:</p>
  
  <pre><code>WHERE applicantID = 3 SET group = 4
  </code></pre>
  
  <p>This is a sample of the JSON I am dealing with:</p>
  
  <pre><code>{
      "applicantID" : 3,
      "fullName": "name",
      "value1": 30,
      "value1": 31,
      "value1": 40,
      "value1": 41,
      "value1": "50",
      "value1": "51",
      "group": 0,
      "flag": true,
  },
  {
      "applicantID" : 4,
      "fullName": "name",
      "value1": 30,
      "value1": 31,
      "value1": 40,
      "value1": 41,
      "value1": "50",
      "value1": "51",
      "group": 0,
      "flag": false,
  }
  </code></pre>
