What’s the useDebugValue hook for in React Hooks?

The useDebugValue hook in React is a user tool that allows you to display custom labels for custom hooks in React DevTools. It’s primarily used for debugging and improving the user experience when working with custom hooks.

Understanding the useDebugValue Hook in React:

• Debugging Custom Hooks: When you create custom hooks in React, it can sometimes be challenging to understand their behavior or purpose when inspecting them in the React DevTools. useDebugValue allows you to provide additional context or information about the custom hook’s state or behavior directly in the DevTools.
• Custom Labeling: You can use useDebugValue to label custom hooks with meaningful information, such as the current value of a state variable, the result of a computation, or any other relevant details that help in understanding the hook’s internal state or behavior.
• Improving Developer Experience: By providing descriptive labels, useDebugValue makes it easier for developers to understand what a custom hook does and how it’s being used in a component. This can streamline the debugging process and improve overall code maintainability.
• Conditional Labeling: useDebugValue also supports conditional labeling, allowing you to display different labels based on certain conditions or states within the custom hook. This can be particularly helpful in complex scenarios where the behavior of the hook depends on various factors.
