Regex

Regex, or Regular Expression, is a tool used to find, match, and manipulate patterns in text. It lets you identify specific patterns: do email addresses have valid structures, do the passwords match, or any custom string you need.

You set up a pattern using special symbols, and Regex helps you find exactly what you’re looking for. For example, you can use Regex to pull out all instances of a certain word or to check if a phone number is formatted correctly.

Though it might seem complex at first, Regex is very useful once you get the hang of it. It’s commonly used in programming languages like Python and JavaScript, and can be found in text editors and other tools. In simple terms, Regex helps you quickly search and manipulate specific text inputs based on the patterns you define.
