To implement React Hooks to concentrate on the parent's perspective from a child's perspective, you can use the useContext hook.
import React from 'react';
const ParentContext = React.createContext();
export default ParentContext;
import React, { useState } from 'react';
import ParentContext from './ParentContext';
const ParentComponent = () => {
const [parentState, setParentState] = useState('parent state');
return (
<ParentContext.Provider value={{ parentState, setParentState }}>
<ChildComponent />
</ParentContext.Provider>
);
};
export default ParentComponent;
import React, { useContext } from 'react';
import ParentContext from './ParentContext';
const ChildComponent = () => {
const { parentState, setParentState } = useContext(ParentContext);
const handleOnClick = () => {
setParentState('new parent state');
};
return (
<div>
<p>Parent state from child component: {parentState}</p>
<button onClick={handleOnClick}>Update Parent State</button>
</div>
);
};
export default ChildComponent;
In this example, the ParentComponent passes down the parentState and setParentState functions through the ParentContext Provider. The ChildComponent accesses these values through the useContext hook and can update the parent's state from within the child component.
