Event Loop — asosiy tushuncha
JavaScript bitta ipli (single-threaded) — bir vaqtda faqat bitta narsa bajariladi. Lekin u bloklamas (non-blocking) ishlaydi. Buning siri — Event Loop mexanizmi.

Call Stack → bo'shasa → Microtask Queue → bo'shasa → Macrotask Queue

4 ta asosiy tushuncha
Call Stack — hozir bajarilyotgan kod. push (kirdi) / pop (chiqdi).
Web/Node APIs — setTimeout, fetch, fs.readFile kabi asinxron ishlar shu yerda kutadi. Stack ni bloklamaydi.
Microtask Queue — Promise.then(), queueMicrotask(), MutationObserver. Stack bo'shagandan keyin birinchi navbatda, barchasi bajariladi.
Macrotask Queue — setTimeout, setInterval, I/O. Microtask queue to'liq bo'shagandagina navbat keladi.

console.log("1");           // Call Stack — hoziroq

setTimeout(() => {
  console.log("4");         // Macrotask — eng oxirida
}, 0);

Promise.resolve()
  .then(() => console.log("3"));  // Microtask — setTimeout dan oldin!

queueMicrotask(() => {
  console.log("2.5");       // Microtask — Promise dan oldin (qo'shilish tartibida)
});

console.log("2");           // Call Stack — hoziroq

// Natija: 1 → 2 → 2.5 → 3 → 4
