Interpolation

Instructions

Create a function called interpolation that takes an object with 5 properties step, start, end, callback and duration. This function must calculate the interpolation points, (x, y), from the start position to end position depending on the number of steps. All the points must be calculated in the duration time.

For each interpolation point you must call callback function with parameter - interpolation point ([x, y]). Each interpolation point should be calculated with interval of duration / step.

Example

step = 5
start = 0
end = 1
duration = 10

   t

10 |_______________. <- execute callback([1.0, 10])
