Explanation: The term “metacharacters” refers to this group of characters in regular expressions. This includes the dollar sign ($), the circumflex (), and the dot wildcard. Metacharacters are characters that have a specific meaning within the context of a regex pattern. They may be used to specify quantifiers, places in the string, or classes of characters. Within the framework of regular expressions, these characters do not match one another literally but rather have a special meaning.
