XML Bomb (Billion Laughs) Tutorial 🎯

Welcome to CodeYourCraft! Today, we're diving into the world of XML (Extensible Markup Language), a flexible text format used to store and transport data. Let's get started! 🎉

What is XML? 📝

XML is a markup language that allows you to create your own tags to define data structures. It's human-readable, platform-independent, and easy to understand. In this tutorial, we'll explore a fun and infamous XML concept called the XML Bomb (Billion Laughs).
