What is Regex?
Think of it as a 'Super Search' tool. Instead of searching for a specific word like 'apple', you can search for patterns like 'any word that starts with A' or 'any text that looks like a phone number'.
Why use it?
It saves hours of manual work. Imagine finding every email address in a 100-page document. With Regex, you can do it in a split second. It's essential for validating forms (like checking if a password is strong enough) and cleaning up messy data.
How it works
It matches text like a puzzle piece. You create a 'pattern' using special symbols (e.g., '\d' means 'any number'). The computer scans your text and highlights exactly where that pattern fits. It's like a filter that only lets specific shapes pass through.
