Product

Create a transducer that will produce the given number of values before it stops. So, for example, calling forSteps(2) will create a transducer that produces 2 values before it stops.

The number of steps must be non-negative. 0 steps means a transducer that stops immediately. 1 step will produce the start value for a half-open interval and the stop value for a closed interval.

Transform the output of this interpolation with the given function.

Combine this Interpolation in parallel with that Interpolation.

Apply an easing function to this interpolation.

Map the range in this interpolation to 0.0 and 1.0, pass through the given easing function, and then map back to the original domain.
