Regular Expression (regex) Resources

Regular expressions (often referred to as regex) are a way to describe patterns in text so that a computer / software can find what you’re looking for or validate the text against a defined rule. They're used to search, validate, or pull out specific pieces of text from larger strings (like emails, numbers, or words).
