Finds the last occurrence of a substring within a String object.
"String Literal".lastIndexOf(substring, startindex)
The lastIndexOf method syntax has these arguments:
Part Description substring The substring to search for within the String object. startindex An optional integer value specifying the index to begin searching within the String object. If omitted, searching begins at the end of the string.
The lastIndexOf method returns an integer value indicating the beginning of the substring within the String object. If the substring is not found, a -1 is returned.
If startindex is negative, startindex is treated as zero. If it is larger than the greatest character position index, it is treated as the largest possible index.
Searching is performed right to left. Otherwise, this method is identical to indexOf.
