use-functional-setstate-updates

What problem does it solve?

This Skill addresses the common React issue of stale closures and unnecessary re-renders that occur when updating component state based on its previous value.

Core Features & Use Cases

• Functional Updates: Utilizes the functional update form of setState to ensure operations always use the latest state.
• Stable Callbacks: Enables the creation of stable useCallback references by eliminating state dependencies.
• Use Case: In a to-do list application, consistently adding or removing items without causing re-renders or stale data by using functional setState updates within event handlers.

Quick Start

Apply the functional setState update pattern to your React component's state logic.
