There is no reason to use the substring method. Use slice instead. string.toLocaleLowerCase( ) The toLocaleLowerCase method produces a new string that is made by converting this string to lowercase using the rules for the locale. This is primarily for the benefit of Turkish because in that language 'I’ converts to 1””
