setTimeout(), setInterval(), and requestAnimationFrame()

setTimeout is faster than setInterval
setInterval is more accurate
setTimeout executes once, setInterval repeatedly
Key differences between setTimeout and setInterval: 1) setTimeout executes callback once, setInterval repeatedly, 2) setInterval doesn't wait for callback completion, 3) setTimeout requires manual rescheduling for repetition, 4) setInterval can cause callback overlap issues, 5) setTimeout offers more precise control over timing, 6) Different use cases for one-time vs recurring operations.
setTimeout uses less memory
