Code was refactored to use point-free style and functional utilities were reformatted to make them easier to read.

Add support for big lists

trampoline utility function wraps now arrayShuffle to fix missing PTC handling in the default Node 6 env and all browsers that don't support it.

Add support for duplicated items in the list

Refactored algorithm to explicitly update the picked index. Without this change algorithm was working properly only when the unique values were provided.
