Analog of the
Easing module from React Native.
A stepping function, returns 1 for any positive value of
A stepping function, returns 1 if
n is greater than or equal to 1.
A linear function,
f(t) = t. Position correlates to elapsed time one to one.
A basic inertial interaction, similar to an object slowly accelerating to speed.
A quadratic function,
f(t) = t * t. Position equals the square of elapsed time.
A cubic function,
f(t) = t * t * t. Position equals the cube of elapsed time.
A power function. Position is equal to the Nth power of elapsed time.
A sinusoidal function.
A circular function.
An exponential function.
A basic elastic interaction, similar to a spring oscillating back and forth.
Default bounciness is 1, which overshoots a little bit once. 0 bounciness doesn't overshoot at all, and bounciness of N > 1 will overshoot about N times.
Animated.parallel() to create a basic effect where the object animates back slightly as the animation starts.
Provides a basic bouncing effect.
Provides a cubic bezier curve, equivalent to CSS Transitions'

Runs an easing function forwards.
Runs an easing function backwards.
Makes any easing function symmetrical. The easing function will run forwards for half of the duration, then backwards for the rest of the duration.
