Question: How to get the parent component name in React?
Answer: In React, you can use the `displayName` property to get the name of the parent component. The `displayName` property is an optional static property that you can define on a React component class.
Here’s an example:
class ParentComponent extends React.Component {
static displayName = 'ParentComponent';
render() {
return (
);
}
}
class ChildComponent extends React.Component {
render() {
// Access the parent component name
const parentComponentName = this.constructor && this.constructor.parentDisplayName;
return (
Parent Component Name: {parentComponentName}
);
}
}
ReactDOM.render(, document.getElementById('root'));
In this example, the `ParentComponent` sets its `displayName` as `’ParentComponent’`. Then, in the `ChildComponent`, you can access the parent component name using `this.constructor.parentDisplayName`.
Finally, when rendering the `ParentComponent`, the parent component name will be displayed in the child component.
Hope this helps!

Explanation:
To get the parent component’s name in React, you need to make use of the `displayName` property. The example code above demonstrates it.
In React, the `displayName` property is a static property of a React component class. By setting the `displayName` property, you can assign a name to your component, which can then be accessed by child components.
In the example, there are two components: `ParentComponent` and `ChildComponent`. The `ParentComponent` sets its `displayName` as `’ParentComponent’`, and it renders the `ChildComponent` as its child.
Inside the `ChildComponent`, you can access the parent component’s name using `this.constructor.parentDisplayName`.
Finally, by rendering the `ParentComponent` and attaching it to the DOM element with the id `’root’`, you will see the parent component’s name displayed in the child component.
Note that in the real implementation, you should use proper React component imports, like `import React from ‘react’;`, and you may need to include the necessary libraries or scripts for syntax highlighting in code blocks.
