Animation
The timeline and tweens

In Janvas a timeline is like a history: a tween is a state of the object — what changes, with the end values — that holds from one time to another. You animate by moving the playhead and changing the object: the tween picks up the changes on its own.

What a tween carries, how it is evaluated, how you write it by changing the object.

How the value runs from start to end.
