In this episode, we’ll dive into the foundation of any programming language: variables and data types! Mastering these early will make everything you do in JavaScript much easier and more powerful. 🚀

🎯 Here’s what we’ll cover:
• Understand what a variable is: a container for storing data.
• Learn how to declare variables using let and const — and briefly touch on var as older legacy syntax.
• Explore primitive data types in JavaScript: strings, numbers, booleans, null, and undefined.
• Use typeof to inspect and understand the type of any value.
• Follow best practices with naming conventions like camelCase and choosing clear, descriptive names.

🎥 Visual Walkthroughs:
• See real examples of variable declarations and data types in action.
• Inspect types live using the console to build intuition.
• Highlight common quirks (like why null shows up as “object”!).

By the end of this episode, you’ll have a strong grip on creating variables and recognizing the key types of data in JavaScript! 💥
