-Creates an array of elements, grouped based on the position in the original arrays and using function as the last value to specify how grouped values should be combined.
+Creates an array of elements, grouped based on the position in the original arrays and using a function to specify how grouped values should be combined.
 
 - Check if the last argument provided is a function.
 - Use `Math.max()` to get the longest array in the arguments.
-- Creates an array with that length as return value and use `Array.from()` with a map-function to create an array of grouped elements.
-- If lengths of the argument-arrays vary, `undefined` is used where no value could be found.
-- The function is invoked with the elements of each group `(...group)`.
+- Use `Array.from()` to create an array with appropriate length and a mapping function to create array of grouped elements.
+- If lengths of the argument arrays vary, `undefined` is used where no value could be found.
+- The function is invoked with the elements of each group.
