stringsHasSuffix

The stringsHasSuffix function is a utility commonly found in programming libraries for checking if a given string ends with a specific suffix. It takes two string arguments: the main string to be examined and the potential suffix. The function returns a boolean value: true if the main string concludes with the suffix, and false otherwise. This operation is case-sensitive by default in most implementations, meaning that "Hello" does not have the suffix "lo" but would if compared case-insensitively.

This function is essential for various text processing tasks. For example, it can be used to identify file extensions by checking if a filename string ends with ".txt" or ".jpg". It's also useful in parsing input strings, validating user-entered data, or extracting specific parts of a larger text. The implementation typically involves comparing the characters of the main string, starting from the position that corresponds to the length of the suffix minus one, with the characters of the suffix. If all characters match consecutively up to the beginning of the suffix within the main string, the function returns true. Otherwise, it returns false. Some libraries might offer variations that allow for case-insensitive comparisons.
