🤔 What is it?
Okay, let me explain! A **Regular Expression** (or **regex** for short) is like a special code that helps you find or fix things in text. For example, if you want to find all the email addresses in a big paragraph, you can use a regex! 📧
The **Regular Expression Tester** is a tool that helps you use these special codes. It’s like a sandbox where you can play with your regex and see what happens! 🎮👾

Ready to try it out? Here’s how you can use the Regular Expression Tester:
Step 1: Enter Your Text First, you need some text to work with. You can type something in the input field or paste some text you found. For example, let’s paste this:
``` You can email me at [email protected] or call me at 123-456-7890. ```
