Writing the constructor() method

Let's look at the constructor method of our App.js file and the preliminary state it initializes, as follows:

1. The constructor starts by instantiating the LCMaster and LCabi components we defined earlier, like this:

class App extends Component {  constructor(){ super();  this.LCMaster = LCMaster; this.LCabi = LCabi;

2. Next, it sets the app name (GreenGables Bank) and binds our methods so that they can be accessed from the child components, as follows:

this.appName = 'GreenGables Bank';this.closeTab = this.closeTab.bind(this);this.resetApp = this.resetApp.bind(this);this.viewLC = this.viewLC.bind(this);this.viewSingleLC = this.viewSingleLC.bind(this);this.onInputChangeUpdateField = this.onInputChangeUpdateField.bind(this); ...
