React -Zustand

import React, { Component } from "react";

class Counter extends Component {
	// you can either initialize state inside constructor
  	constructor() {
		super();
		this.state = {
			count: 1,
			tags: ["tag1", "tag2", "tag3"],
		};
	}
  	// or initialize the state as class field declaration
  	state = {
		count: 1,
		tags: ["tag1", "tag2", "tag3"],
	};
}

So definieren Sie den Zustand in der React -Funktion

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>
  );
}
