Getting node information

We already have a web3 client instance. We can use the following API to gather information about the current node:

web3.eth.getNodeInfo(callback)

Let's see how this works in the React application that we are building:

1. Insert the following code right after creating the Web3 instance:

const web3 = new Web3('ws://localhost:7545');console.log(web3);web3.eth.getNodeInfo(function(error, result) {    if (error) {      console.error(error);    } else {      console.log('result', result);    }});

2. As soon as you run the application, the console log should contain the following information:

result EthereumJS TestRPC/v2.8.0/ethereum-js

You are making good progress so far. Let's display the node information in the user interface on startup. ...
