Explain unfamiliar code with an AI assistant
Reading code is most of programming. Bots are excellent tutors for unfamiliar code.
What to do
- Paste the code plus how it is called; context beats isolation.
- Ask for a top-down summary, then line-by-line on the hard part.
- Ask what assumptions and edge cases the code relies on.
- Ask it to say "I can't tell from this snippet" instead of guessing about other files.
