How to call Parent function with useState Hook in React?

Question

The ideal result is displaying strings when items in the list are clicked.

Here's the Root Component.

const App = () => {
  const [click, setClick] = useState(null);
  const handleClick = name => {
    setClick(name);
  };
  return (
    <div>
      <Parent handleClick={handleClick} />
      {click && <p>{click} is clicked.</p>}
    </div>
  );
};

and Parent Component.

const Parent = ({ handleClick }) => (
  <div>
    <Child
      name="First Item"
      handleClick={handleClick("First Item is Clicked!")}
    />
    <Child
      name="Second Item"
      handleClick={handleClick("Second Item is Clicked!")}
    />
    <Child
      name="Third Item"
      handleClick={handleClick("Third Item is Clicked!")}
    />
  </div>
);

and Child Component.

const Child = ({ name, handleClick }) => <li onClick={handleClick}>{name}</li>;

Also, the code sandbox link.

I just wondered why the result never is never changed by click.

Problem is that you aren't passing a function to handleClick instead an evaluated value from parent. You code must be

import React from "react";
import Child from "./Child";

const Parent = ({ handleClick }) => (
  <div>
    <Child
      name="First Item"
      handleClick={() => handleClick("First Item is Clicked!")}
    />
    <Child
      name="Second Item"
      handleClick={() => handleClick("Second Item is Clicked!")}
    />
    <Child
      name="Third Item"
      handleClick={() => handleClick("Third Item is Clicked!")}
    />
  </div>
);

export default Parent;
