Timing Animation Loops with requestAnimationFrame in JavaScript
- Animations appear smooth when timed to sync with screen redraws that typically happen 60 times per second using requestAnimationFrame in JavaScript.
- requestAnimationFrame schedules animation code to run just before the next frame is shown, ensuring fluid motion and avoiding stuttering.
- The cycle of website frame processing includes JavaScript work, layout changes, paint, fitting within the window between screen refreshes.
- Using requestAnimationFrame, animations need to align with the window of time between screen refreshes to avoid lag or jumpiness in motion.
- The callback passed to requestAnimationFrame runs at the browser's scheduled time, maintaining synchronization with screen updates.
- requestAnimationFrame adjusts timing automatically based on display refresh rates, ensuring smoother animations without the need for manual adjustments.
- Callbacks with requestAnimationFrame run one per frame, preventing flooding of updates and ensuring everything stays in sync with screen rendering.
- Compared to setInterval or setTimeout, requestAnimationFrame better aligns with screen refreshes for more natural-looking animations.
- The timestamp provided by requestAnimationFrame can be used to control animation speed and adjust motion based on elapsed time.
- By calling requestAnimationFrame within the callback, a loop is created to continue the animation frame by frame, ensuring precise control over timing.
