🐛 The Friday Typo0/5

📖 Story

It's 4:59 PM on Friday. You're about to ship your feature when you spot a typo — 'intialStatus' instead of 'initialStatus' — committed THREE changes ago. In Git this means rebase -i, edit, fix, continue, force push. In jj, you jump back, fix it, and the fix magically flows up through every descendant. Let's go home early. #DontPushOnFriday

Check the log: jj log

You have a stack of 3 changes. The typo is in "Add API call" (change ID wtypo02) — the variable reads "intialStatus" instead of "initialStatus". Type jj log to see the stack.

● Check the log: `jj log`

○ Jump into the old change: `jj edit wtypo02`

○ Fix the typo: `echo "export let initialStatus = -1" > src/api.ts`

○ Describe the fix: `jj describe -m "Fix API call"`

○ Jump back to the top: `jj edit wtypo03`

🧩 The Pre-PR CleanupUnsolved

📖 Story

You've been coding for two days and your stack is a mess. jj log shows: - "WIP" (empty commit, no files) - "fix" (one-line fix with no context) - "actually fix" (should be squashed into the one above) - "Add user dashboard" (the real work) Your team requires clean PRs: no WIP commits, no vague messages, no duplicate fixups. Clean it up before you push.

Goal

jj log -r 'all()' must:

contain "Add user dashboard"
not contain "WIP"
not contain "actually fix"
not contain "(no description set)"

jj Terminal

🧩 Problem: The Pre-PR Cleanup

Squash fixup commits, rename vague descriptions, and reorder a messy stack before opening your PR.

Use the terminal to solve the problem. jj log -r 'all()' will be checked automatically.
