Here is an example code that would work in the same way you’ve described it:

import React, { useState } from "react";
import ReactDOM from "react-dom";

function App() {

  // State to store count value
  const [count, setCount] = useState(0);

  // Function to increment count by 1
  const incrementCount = () => {
    // Update state with incremented value
    setCount(count + 1);
  return (
    <div className="app">
      <button onClick={incrementCount}>Click Here</button>

const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);
