More on writing a useful taskAN EXERCISE TO TRY
Understand a website
through its source.
Start with a small private sample of pages. Give yourself one question to investigate.
- Find a string and inspect its context.
- Trace a shared include to the pages that use it.
- Explain what the evidence establishes—and what still needs a check.
Keep one note: What did you notice that a text match alone didn’t tell you?
