Regular expressions (regex) are powerful tools used in computer science for searching, editing, and manipulating text. They consist of a sequence of characters that define a search pattern, allowing users to match specific string sequences within larger bodies of text. Regular expressions are widely utilized in various programming languages and applications, making them essential for tasks such as data validation, text parsing, and information retrieval. By mastering the syntax and structure of regular expressions, developers can efficiently handle complex string operations, significantly improving their productivity and the effectiveness of their code.
