In turn, useState() gives back the initial state, and a state updater function named setPerson(). In the component, we have also a button to trigger a name change through the changeName() function, which does something apparently harmless: import { useState, useCallback } from 'react' export default function useCounter() { const [count, setCount] = useState(0) const increment = useCallback(() => setCount((x) => x + 1), []) import {useState} from " react "; export function AddUser {const [name, setName] = useState (""); const [email, setEmail] = useState (""); const handleName = (e) => setName (e.

useState () is a built-in function that comes with the React library. import { useState } from "react"; useState () should only be used inside a functional component. Passing useState in children component props to use it Passing useState as props in another component is totally possible. But there’s no benefit in doing so because you can always call useState by importing React at the top of your JavaScript code and call it in all of your components. Here’s the sample code snippet to demonstrate this: Import the useState hook from the 'react' package, then make a call of useState () at the top of the component’s function. Let’s make these change to component: import React, { useState } from 'react'; function Bulbs() { = useState(); return
