Let's continue building our blockchain API. In this section, we are going to interact with our /blockchain endpoint. This means that we will have to import our blockchain from our blockchain.js file:

const Blockchain = require('./blockchain');

We have now imported our blockchain data structure or our blockchain constructor function. Next, we want to make an instance of our blockchain. We can do that as follows:

const bitcoin = new Blockchain();

Now we have an instance of our blockchain constructor function and we have called it bitcoin. You can call this whatever you want, but I'm just going to call it bitcoin to keep it simple.

Let's build on our /blockchain endpoint. All this endpoint is going to do is send our entire blockchain back to whoever called this endpoint. To do that, we are going to add a line that will send...
