import React, { Component } from 'react';import Web3 from 'web3'import Nav from './Components/Nav'import Description from './Components/Description'import Container from './Components/Container'import Shoes from './Items/all'

2. Within the constructor, we initialize the global parameters of the requisite state variables. We also bind the methods that will be accessed by the child components for changing the state, as shown here:

class App extends ...
