# Debugging and Error Messages

The `displayName` property in React helps create better debugging messages. When an error happens, a clear `displayName` helps developers find the problematic component faster. If `displayName` isn't set, React will guess it from the function or class name, but this might not always be correct, especially in complex apps.

# Development Tools

React DevTools, a popular tool for inspecting React component trees, uses the `displayName` property to show component names. This makes it easier to navigate and understand the component hierarchy. Without a proper `displayName`, components might appear as "Component" or "Anonymous," which can be confusing.

# Context Objects

React's Context API also supports the `displayName` property. Setting a `displayName` for context objects helps identify the context in DevTools, making it easier to debug context-related issues.

```javascript
const MyContext = React.createContext();
MyContext.displayName = "MyDisplayName";
```

# ESLint Rules

There are ESLint rules like `react/display-name` that require the use of `displayName` in React components. These rules help keep things consistent and make sure all components have clear names, which is especially helpful in big projects.
