setTimeout(), setInterval(), and requestAnimationFrame()
Which timing function continues to execute when a browser tab is in the background?
In background tabs: 1) setTimeout and setInterval continue executing but may be throttled, 2) requestAnimationFrame pauses completely, 3) Minimum timer intervals may be increased (>1000ms), 4) This behavior helps conserve system resources, 5) Different browsers may implement different throttling policies, 6) Important consideration for web application design.
