What is GSAP
- GreenSock Animation Platform
- A suite of high-performance JS tools for animation
- Create animation with code
Basic Tween
Basic Timeline
Animation Objects
- Tweens and timelines both inherit from an Animation class
- They share the same core methods and properties
play()
pause()
resume()
reverse()
seek()
progress()
restart()
timeScale()
delay()
duration()
isActive()
kill()
startTime()
time()
timeScale()
eventCallback()
...and more
- Your application logic doesn't need to be concerned with which type of Animation object it is dealing with
Demonstrate

Functions Returning Timelines
Re-usable Effects
Create functions that return animations with
complex movement
Tween a tween! Huh?
- progress()
- timeScale()
- time()
Animation objects have numeric,
function-based properties that can
be tweened
Solving Common, Real-world Problems
