</h1>
  
<p id="GFG_UP" style="color:green;">
</p>
  
<button onclick="gfg_Fun()">
    find First
</button>
  
<p id="GFG_DOWN" style="color:green; font-size: 20px;">
</p>
  
<script>
    // Declare an object
    var GFG_object = {prop_1: "GFG_1",
            prop_2: "GFG_2", prop_3: "GFG_3"};
      
    var el_up = document.getElementById("GFG_UP");
    var el_down = document.getElementById("GFG_DOWN");
      
    // Use SON.stringify() function to take object
    // or array and create JSON string
    el_up.innerHTML = JSON.stringify(GFG_object);
      
    // Access the first value of an object
    function gfg_Fun() {
    el_down.innerHTML = GFG_object[Object.keys(GFG_object)[0]];
