What Is a Regular Expression?
A regular expression, commonly called Regex or RegExp, is a sequence
of characters used to search, match, validate and replace text
according to a specific pattern.
Developers use regular expressions for email matching, extracting
phone numbers, checking formats, cleaning text, processing data
and searching through large amounts of content.

\d — Matches a digit from 0 to 9.
\w — Matches a word character.
