"requestAnimationFrame"

`requestAnimationFrame` is a method used in web development to create smooth animations. It tells the browser to run a specific function before the next screen refresh, usually around 60 times per second. This helps animations appear fluid and synchronized with the display's refresh rate, reducing flickering and unnecessary calculations. Instead of repeatedly updating the animation with timer functions, `requestAnimationFrame` optimizes performance by efficiently scheduling updates only when the browser is ready to repaint, making animations smoother and more resource-friendly.
