// setTimeout:
//     Calls a function or evaluates an expression after a specified number of milliseconds.
//     Doesn't mean that the function will be called after the exactly specified interval.
//    Can cause a browser to miss the frame.
// requestAnimationFrame
//    Works similarly to setTimeout 
//    called right before the next repaint in the browser occurs.

const timestamp = setTimeout(() => {...}); // runs as frequently as possible
const requestId = requestAnimationFrame(() => {...}); // runs once per frame

clearTimeout(timestamp); // clear previously added timeout
cancelAnimationFrame(requestId); // cancel an animation frame request
