• In computing, Regular Expressions (regex) serves as a powerful search tool that helps you find, replace, or match text in a document based on defined patterns or sequences.
• Think of it as Swiss Army Knife for working with text, most often used for pattern matching and fuzzy searches over text and documents.
• It looks a bit like an alien language, but there's only about 10-20 "words" or concepts you need to understand to be effective. Check out Table of Elements for most of the language.
