To optimize GSAP animations for 60fps, animate transform and opacity properties to minimize layout and paint operations, and batch reads and writes to prevent layout thrashing.

Layout thrashing in GSAP animations happens when reading and writing layout properties interchangeably. Fix it by batching DOM reads and writes separately to prevent the browser from recalculating styles repeatedly.

Use the will-change CSS property to hint browsers about elements that will animate, but avoid overusing it on unnecessary elements to prevent performance pitfalls and excessive memory consumption.

For GSAP performance on low specification devices, avoid animating width and height, use transform and opacity instead, and minimize paint operations to ensure smooth and responsive web animations.

Animating width and height in GSAP causes jank because it triggers layout recalculations and repaints. Animating transform and opacity avoids these expensive operations, maintaining smooth animation performance.

You can check GSAP animations for performance bottlenecks before deploying by analyzing them against optimization guidelines, ensuring transform usage and batched operations prevent poor user experience.
