ASYNCHRONOUS CODE
const p = document.querySelecter('.p');
setTimeout(() => {
// ASYNCHRONOUS code NON-Blocking
p.textContent = 'My name is Jonas!';
}, 5000);
p.style.color = 'red';
- 👉 Asynchronous code is executed after a task that runs in the “background” finishes;
- 👍 Asynchronous code is non-blocking;
- 👉 Execution doesn’t wait for an asynchronous task to finish its work;
- 👉 Callback functions alone do NOT make code asynchronous!
