import React from "react";
import ReactDOM from "react-dom";

function App() {
  return (
    <div className="App">
      <input
        type="text"

In this step, you’ll set the initial state on a component by assigning the initial state to a custom variable using the useState Hook. To explore Hooks, you’ll make a product page with a shopping cart, then display the initial values based on the state. By the end of the step, you’ll know the different ways to hold a state value using Hooks and when to use state rather than a prop or a static value.,For example, in this component, you have two pieces of data that will change based on user actions: the cart and the total cost. Each of these can be stored in state using the above Hook.,You now have some JSX that uses the .map method to iterate over the array and display the products.
