Learn GSAP with Real Code Examples
Updated Nov 26, 2025
Architecture
Tween engine - core numeric interpolation
Timeline engine - orchestrates multiple tweens
Plugins - extend tween capabilities
Render loop - efficient updates per animation frame
Ease functions - define motion dynamics
Rendering Model
Tween interpolates numeric values over time
Timeline orchestrates multiple tweens and callbacks
Render loop efficiently updates properties per animation frame
Plugins extend rendering behavior
Easing functions modify rate of change for natural motion
Architectural Patterns

Design Principles
High-performance and smooth animations
Flexible, chainable, and modular API
Cross-browser consistency
Extensible via plugins
Precise control over timing and sequencing
Scalability Guide
Use timelines for grouped sequences
Batch DOM updates to reduce reflows
Reuse tweens instead of creating new ones
Use ScrollTrigger for scroll-based triggers
Optimize large number of animated elements
Migration Guide
Convert CSS transitions to GSAP tweens for precise control
Replace jQuery animations with GSAP for performance
Refactor chained animations into timelines
Register plugins for scroll or morphing effects
Test timing and easing for consistency
