Example

Feedback you can act on

Review mode groups findings by severity and shows the fix for each, so you can improve the code before the pull request.

Bugs and unhandled edge cases
Security smells like injection or missing encoding
Naming, structure and readability
Performance and unnecessary work

Review this:

async function getUser(id: any) {
  const r = await fetch("/api/users/" + id);
  return r.json();
}

1. id: any — type it as string. 2. No r.ok check: a 404 returns an error body as if it were a user. 3. Encode the id with encodeURIComponent. 4. Add a return type, e.g. Promise<User>.
