Go string manipulation functions
Article Introduction：The key to processing strings in Go language is to master the core functions and efficient techniques in the standard library. The strings package provides common operations, such as converting case, de-spaces, judging substrings, splitting and splicing strings; for example, using Split and Join combinations to achieve flexible string processing. The replacement and cropping functions are implemented by ReplaceAll, TrimPrefix and TrimSuffix to effectively clean up unnecessary characters or specific pres and suffixes.
