React useEffect Dependency Checker

Paste a useEffect, useMemo, or useCallback call and see identifiers used in the body vs declared in the deps array - a fast eyeball check for what might be missing.

Paste a useEffect / useMemo / useCallback call

Possibly missing from deps: AbortController, fetchUser, setUser, page

Used in the callback

AbortController, fetchUser, userId, setUser, page

Declared in deps array

userId

Regex heuristic, not scope-aware AST analysis - a fast eyeball check, not a replacement for ESLint's exhaustive-deps rule.
