Regular Expressions (Regex)

Why Participate

Regular Expressions, also known as “Regex” (pronounced REJ-ex) are an incredibly powerful way of representing or specifying specific patterns found in text. They are extremely useful for data cleaning and validation - allowing you to do highly sophisticated pattern matching that can be used to extract, modify, replace, select, and/or split on strings that do or don’t match the specified regex. Most common code editors, such as VSCode and Notepad++ have built-in regex capabilities.

Via participation in this workout, you will learn how to build and apply regex expressions, as well as learn how to use the best modern online tools for creating, testing and managing your regex code.
