Parameters
- anyOf
An array of Unicode characters, any one or more of whose characters you want to find in the current String object. - startIndex
The starting index number for the search.
Return Value
The character position of the last occurrence in the current String object of any character within the specified array, or -1 if no such character is found.
Remarks
The search begins at the first character position in the current String object and proceeds backward toward the beginning of the string until either the anyOf parameter is found or the beginning of the string is reached (whichever occurs first).
