Nit
ELI5 — The Vibe Check
A nit (short for nitpick) is a tiny, non-blocking code review comment about something that doesn't really matter but someone felt strongly enough to mention. 'Nit: add a space here.' 'Nit: this variable name could be clearer.' They're the developer equivalent of correcting someone's grammar at a party. Technically right, socially debatable.
Real Talk
In code reviews, a 'nit' is a minor suggestion that doesn't block approval — typically style preferences, naming conventions, or formatting choices. Prefixing with 'nit:' signals that the comment is optional and the reviewer would approve regardless. Over-nitpicking can slow down teams, while appropriate nits maintain code consistency.
When You'll Hear This
"Nit: rename this to 'isActive' instead of 'active'." / "It's just a nit, don't let it block the merge."
