When Should requestAnimationFrame Be Favored Over setInterval and setTimeout?

requestAnimationFrame: A Superior Alternative to setInterval and setTimeout

While setInterval and setTimeout can be utilized for animation purposes, they fall short in providing the optimal user experience compared to requestAnimationFrame.

Key Benefits of requestAnimationFrame:

• High-Quality Animation: requestAnimationFrame synchronizes the animation callbacks with the display's refresh rate. This ensures a smooth, flicker-free presentation. In contrast, setInterval and setTimeout may introduce inconsistencies due to their fixed time intervals.
• High Precision Timers: requestAnimationFrame delivers high-resolution timers through the provided timestamp parameter, allowing for accurate animation timing and delta time calculations.

Specific Advantages Over setInterval and setTimeout:

• Eliminates Flicker: requestAnimationFrame mitigates flickering by aligning the rendering with the display's refresh cycle.
• Reduces Frame Skips: By aligning with the refresh rate, requestAnimationFrame minimizes frame skips, resulting in a smoother animation.
• Provides Delta Time: The timestamp parameter of requestAnimationFrame allows for the calculation of delta time, which is crucial for smooth animations.

Limitations of requestAnimationFrame:

• Unknown Frame Rate: The frame rate varies depending on the device's refresh rate, which can be inconsistent across devices.
• Forced Pause: requestAnimationFrame halts when the page is not visible, potentially affecting the continuity of the animation.
• Unsynced Rendering: Some devices may ignore the display's refresh rate, leading to unoptimized rendering.

Conclusion:

If you prioritize high-quality, precise, and consistent rendering, requestAnimationFrame emerges as the superior choice over setInterval and setTimeout. It ensures a seamless user experience by synchronizing with the device's refresh rate and providing high-resolution timers.
