GreenSock, a longstanding JavaScript animation library, has released GSAP 3, offering significant improvements and new features while maintaining backward compatibility. This version simplifies the API by consolidating previous core modules into a single gsap object, reducing file size, and rebuilding the core as modern ES modules. It introduces timeline defaults, allowing child tweens to inherit properties and adhere to the DRY principle. Advanced features like the removal of stagger methods in favor of parameters in the vars object, new random capabilities for creating randomized effects, and relative position prefixes enhance animation control. GSAP 3 also offers 15 new utility methods and keyframes for defining multiple animation states, making it a robust tool for developers to create intuitive and interactive websites. The library can be integrated into projects via CDN or package managers, ensuring ease of use across different development environments.
