I would solve your problem with recursive function.

Steps:

  1. Create a recursive function which will receive one parameter
  2. If array length is larger than 0 continue with the function body
  3. Shift array ( removes the first item from an array and store it into the variable)
  4. Call our function and execute AJAX call with provided parameters, and also pass our array
  5. When AJAX call is finished call our recursive function and pass our array to it

Code:

function myRecursiveFunction(myArray){
   if(myArray.length == 0) return;

   //remove first item of an array then store it into variable item
   var item = myArray.shift(); 
   //call our method which will execute AJAX call to server
   ajaxRequest(item[0], titleCase(item[1]), myArray);
}

function ajaxRequest(token, title, myArray) {
  $.post(APP_URL + "/message/send", {
    "_token": Laraveltoken,
    title: title,
    token: token
  }, function(data, status) {
    //When Done start next request
  }).always(function(){
    //call our recursive function
    myRecursiveFunction(myArray);
   });;
}

You can use async.js for multiple asynchronous operation.

https://caolan.github.io/async/

Examples:

async.parallel([
    function(callback) { ... },
    function(callback) { ... }
], function(err, results) {
    // optional callback
});

async.series([
    function(callback) { ... },
    function(callback) { ... }
]);
