Adds store.count() and a 'count' command in notes.js that prints "You have N notes." (singular for one note). Lists the command in the help text and README, and adds a test that count() matches the number of stored notes. All four tests pass. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

What
countcommand:node notes.js countprintsYou have N notes.(notefor exactly one).store.count()inlib/store.jsreturns the number of stored notes.countadded to the help text innotes.jsand to the command list in the README.count()equalsall().length.Why
Lets users see how many notes they have without listing them all (Lesson 3 task).
Testing
npm test: 4/4 pass (3 existing + 1 new).node notes.js countprintsYou have 0 notes.on an empty store.For reviewers
The new test reads the real
notes.json(viastore) rather than a fixture, so it only checks thatcount()andall()agree, not specific numbers.🤖 Generated with Claude Code
