DOM-Operations and querySelector are heavy operations. getElementById is much faster than querySelector('#id'), especially if called often (e.g. in loops and intervals).
If multiple operations need to be done on an element, avoid selecting the element multiple times but cache it (store it in a variable or in an object) instead.
