How to notify after multiple AJAX call completes

I have 3 ajax calls on my page. Second ajax call will call on success of first and third ajax call will call on success of second. Each response returns multiple records so I have to make a while loop to go through each records and make corresponding AJAX call. I need to pass data from while loop to subsequent AJAX call.

I want to print the console like:

First
Second
Third

First
Second
Third

First
Second
Third

All Asyc Call complete

However, it is showing me

First
First
First

All Asyc Call complete

Second
Second
Second

Third
Third
Third

// First Ajax Call
$.ajax({
  
  success: function(response1) {
    
    while(response1.next()) {
    
      console.log("First");
      
      // Second Ajax Call
      $.ajax({
        
        success: function(response2){
          
          while(response2.next()) {
          
            console.log("Second");
            
            // Third Ajax Call
            $.ajax({
              
              success: function(response3){
              
                while(response3.next()) {
                  console.log("Third");
                }
                
              }
              
            })
            
            
          }
        
        }
        
      })
    
    }
      
      
  }

})
console.log("All Asyc call completes");

You can do something like this:

$(document).ajaxSuccess(function() {
    if( ajax_sucess_counter == 3 ) alert('the 3 ajax calls are completed');
});

var ajax_sucess_counter = 0;

$.ajax({
    //...
    success: function(){
        // ...
        ajax_sucess_counter++;
    }
});

Using deferred objects:

$.when( $.ajax('call1.php'), $.ajax('call2.php'), $.ajax('call3.php') ).done(function() {
      alert('the 3 ajax calls are completed');
}});

You have all information and more examples at jQuery Docs.
