Okay, so imagine you have a big box of LEGO pieces 🧱. Some are red, some are blue, and some have stars on them. Now, you want to find all the red pieces with stars. Instead of looking through the whole box, you can use a special tool to find them fast! That’s what a **Regular Expression (regex)** does! 🌈
A **regex tester** is a tool that helps you test these special patterns. It’s like a helper that looks at your text and finds the pieces you want! 🔍
