React, useEffect, and Stale Closures: How to Avoid Them with Dependencies and useRef

Read Original

This technical article dives into a common React problem: stale closures within the useEffect hook. It explains the concept, demonstrates a classic bug with a missing dependency, and provides two solutions: properly using the dependency array to recreate the effect, and using useRef to access up-to-date values without effect recreation. Includes practical code examples for each scenario.
