I see that both functions, Index and FindOneOf, pretty much do the same thing:
As you can see in the example you shared , index always look for the exact search string or character from the main string and the 3rd parameter helps to identifies the occurrence.
But Findoneof search of any one character from your search sting based on there occurrence with in the main string. Which occur first, its position is taken as accordingly.
