<!DOCTYPE HTML>  
<html>   
<head>  
    <title>  
      JQuery | deferred.resolve() method 
    </title> 
    <script src="https://code.jquery.com/jquery-3.5.0.js">

        GeeksForGeeks   
    </h1>  
    <p id="GFG_UP">  
    </p> 
    <button onclick = "Geeks();"> 
    click here 
    </button> 
    <p id="GFG_DOWN">  
    </p> 
    <script>  
        var el_up = document.getElementById("GFG_UP"); 
        el_up.innerHTML = "JQuery | deferred.resolve() method"; 
        function Func(val, div){ 
          $(div).append(val); 
        } 
        function Geeks() { 
            var def = $.Deferred(); 
            def.done(Func); 
            def.resolve( 
'resolve() method is called with arguments  
           and Deferred object is resolved', '#GFG_DOWN') 
        }

        function Func(){ 
          $('#GFG_DOWN').append( 
"resolve() method is called without arguments
