The JavaScript console is a powerful tool for debugging and testing code. Here are some common examples:

1. Basic Output

console.log("Hello, World!"); // 🟢 Output to console
console.error("An error occurred!"); // 🔴 Error logging
console.warn("This is a warning!"); // ⚠️ Warning message

2. Debugging Tips

  • Use console.log() to track variable values
  • Combine with template literals: 
    console.log(`Value: ${variable}`);
  • Check the Developer Tools (F12) for real-time output
  • Use console.table() for structured data: 
    console.table([{ name: "John", age: 30 }, { name: "Jane", age: 25 }]);

3. Advanced Applications

  • Logging Objects: 
    const user = { name: "Alice", role: "developer" };
console.log(user);
  • Timed Logging: 
    setTimeout(() => console.log("Delayed log"), 2000);
  • Conditional Logging: 
    if (x > 10) console.log("x is greater than 10");
