Debugging Strategies

Let's explore three different approaches to debug using Memex

1. The Scientific Method for Debugging

1. Observe: What exactly is happening? What did you expect to happen?

2. Hypothesize: What might be causing the issue?

3. Test: Make a small change to test your hypothesis

4. Analyze: Did the change fix the issue? If not, what did you learn?

5. Repeat: Form a new hypothesis based on what you learned

"When I click the 'Save' button, nothing happens. I expected the form data to be saved and a confirmation message to appear. Let's check if the button click event is being triggered at all."

2. Divide and Conquer

1. Isolate components: Test parts of the system separately

2. Binary search: If you have a large codebase, test the middle to narrow down where the problem is

3. Eliminate variables: Simplify until you find the minimal case that reproduces the issue

"Let's create a simple test page with just the form component to see if it works in isolation. If it does, we know the issue is in how it interacts with other components."

3. Logging and Monitoring

1. Strategic console logs: Add logs at key points in the code flow

2. State tracking: Log the state of important variables

3. Input/output validation: Verify data at entry and exit points

"Can we add logs to track the form data at three points: when the user inputs it, when the save button is clicked, and when we try to send it to the server?"
