How does Google Analytics parse the request queue?

Question

Google

Hello!
Asynchronous Google Analytics works through a queue. Initially, an array is created, calls are added to it, and when either is loaded, the calls are executed. The question is how does this happen?
Let's assume that we have collected such an array:

var funcQuery = [
  ['firstFunc', 'UA-XXXXX-X'],
  ['secondFunc', '1'],
  ['thirdFunc', {"data":123}, 'bla bla'],
];

How then it is possible to make execute of functions from this array?
Thanks in advance!

Answer 1

window.firstFunc = function (p) {
  console.log('firstFunc', p);
}

window.secondFunc = function (p) {
  console.log('secondFunc', p);
}

window.thirdFunc = function (o, p) {
  console.log('thirdFunc', o, p);
}

var funcQuery = [
  ['firstFunc', 'UA-XXXXX-X'],
  ['secondFunc', '1'],
  ['thirdFunc', {"data":123}, 'bla bla'],
];

setTimeout(function () {
  for (var i = 0; i < funcQuery.length; i++) {
    window[funcQuery[i][0]].apply(null, funcQuery[i].slice(1));
  }
}, 2000);
