import gsap from 'gsap';

function AnimatedComponent() {
    useEffect(() => {
        gsap.to(".myComponent", {opacity: 1, y: -20, duration: 1});
    }, []);

    return (
        <div className="myComponent" style={{opacity: 0}}>
            This component fades in!
        </div>
    );
}

Here, useEffect is used to handle component lifecycle events, triggering the GSAP animation when the component mounts.
