Power Query M formula language standard library: List.Transform

List.Transform applies a function on each element of a list and returns a list whose elements correspond to the function's return value.

The following example evaluates to {4, 3, 3, 5, 4, 4, 3, 5, 5, 4}:

let
   numbers = {"zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine"}
in
   List.Transform(numbers, Text.Length)
