What are Variables?

Variables are like containers that store information in your program. Think of them as labeled boxes where you can put different types of data - numbers, text, true/false values, and more!

💻 Code Example:

// Creating variables with 'let'
let username = "Player1";
let score = 100;
let isActive = true;

// You can change the value later
score = 150;
console.log(score); // Shows: 150

💡 Tip: Open your browser console (F12) and try typing these examples!

📝 Key Points:

  • Variables store data in your program
  • Use descriptive names for variables
  • Variable values can be changed
