• Regexp: A RegExp object. Response for matching the replaced parameter #2.
• Substr: a string that is replaced by newSubStr.
• NewSubStr: it replaces the substring received from the parameter #1.
• Function: a function is called to create a substring.
• Flags: Any combination string containing the regular expression flag: g-global match, I-case-insensitive, and m-matched multiple rows. This parameter is only used if the first parameter is a string.
