Update JSON Array with React.js
<p>Here is my JSON Array.</p>

<pre><code> rows : [
   { 
     "id":1,
     "first_name":"William",
     "last_name":"Elliott",
     "email":"welliott0@wisc.edu",
     "country":"Argentina",
     "ip_address":"247.180.226.89",
     "notificationType": [
       {
         "type": "update",
         "text": "New Update"
         "selected":null
       },
       {
         "type": "user",
         "text": "New User"
         "selected":null           
       }
     ]
   }
 ]
</code></pre>

<p>I need to update this array.For example let's take care of notificationType data.</p>

<p>I want to update "selected":null value to "selected":true.</p>

<p>How can I do this?</p>
