Wiggle API / Easing

Type Alias: Easing

Easing = NamedEasing | Spring

How a value moves between two states: either a named curve or a spring. The same ease is accepted everywhere motion is defined (keyframes, the tween verbs, interpolate, and the entrance verbs). A spring is time-scaled to the interval it is given, so its overshoot settles by the interval's end.
