📚 Topic Summary
Debugging logic in JavaScript is like being a detective for your code! It involves identifying and fixing errors (bugs) that cause your program to behave unexpectedly. In an unplugged activity, we simulate this process without actually using a computer. We focus on understanding the flow of instructions and identifying where things go wrong by tracing the code's execution step-by-step.
This approach helps build a strong foundation in computational thinking and problem-solving before diving into complex coding environments. By manually tracing code and identifying errors, students develop a deeper understanding of how programs work and how to find and fix problems efficiently. This is a foundational skill for any programmer!

Answer Key: 1-B, 2-A, 3-D, 4-C, 5-E
✍️ Part B: Fill in the Blanks
Complete the paragraph below using the following words: Debugging, Algorithm, Syntax, Logic, Errors.
When writing code, it's important to ensure that the _________ is correct, following the rules of the programming language. An _________ is a sequence of steps to solve a problem. _________ involves finding and fixing __________ in your code. A common type of error occurs when the _________ isn't correct, which can cause the program to fail.
Answer: Syntax, Algorithm, Debugging, Errors, Logic
🤔 Part C: Critical Thinking
Imagine you are debugging a program and find that the output is not what you expected. What are three questions you would ask yourself to help identify the source of the problem?
- 🧐 Have I tested all possible inputs and outputs for this section of the program?
- 📝 Is my understanding of the algorithm flawed? Are there implicit edge cases I am unaware of?
- 💡 Is there any external software or libraries interacting with my program? Do these interactions cause the unexpected behaviour?
