Debugging in Scratch Quiz: Test Your Bug-Fixing Skills

📚 Quick Study Guide

• 🔍 Debugging is finding and fixing errors (bugs) in your code.
• 🛠️ Common Scratch bugs include incorrect variable values, infinite loops, and incorrect event handling.
• 💡 Use the "stop sign" button to halt infinite loops.
• 👀 Check variable values using the "watch" block.
• 🐾 Step through your code to identify where the bug occurs.
• 📝 Add comments to your code to explain what each section does; this helps with debugging later.
• ✅ Test your code frequently after making changes.
