react hooks send data from child to parent
const { useState } = React;
function PageComponent() {
const [count, setCount] = useState(0);
const increment = () => {
setCount(count + 1)
}
return (
<div className="App">
<ChildComponent onClick={increment} count={count} />
<h2>count {count}</h2>
(count should be updated from child)
</div>
);
}
const ChildComponent = ({ onClick, count }) => {
return (
<button onClick={onClick}>
Click me {count}
</button>
)
};
ReactDOM.render(<PageComponent />, document.getElementById("root"));
