Regular Expressions

Regular expressions, often abbreviated as regex, are sequences of characters that form a search pattern. They are used in computing to find and manipulate text. For instance, if you want to locate all email addresses in a document, you can use a regex to specify the format of an email. This tool can match simple patterns like specific words or complex ones, such as phone numbers or dates, making it versatile for various text-processing tasks. Essentially, regex is a powerful way to efficiently search through and edit text based on specific criteria.
