do we need state for showing date react.js code example

Example 1: displaying the date react

import React from "react";

export default class App extends React.Component {
  state = {
    date: ""
  };

  componentDidMount() {
    this.getDate();
  }

  getDate = () => {
    var date = new Date().toDateString();
    this.setState({ date });
  };

  render() {
    const { date } = this.state;

    return <div>{date}</div>;
  }
}
}

export default App;

Example 2: how to define state in react function

import React, { useState } from 'react';

function Example() {
  // Declare a new state variable, which we'll call "count" 
  const [count, setCount] = useState(0);
  return (
    <div>
      <p>You clicked {count} times</p>
      <button onClick={() => setCount(count + 1)}>
        Click me
      </button>
    </div>
  );
}
