MyBlockchain.js

var blockchain = new Blockchain(4);
var block1 = blockchain.newBlock("Second Block");
blockchain.addBlock(block1);
var block2 = blockchain.newBlock("Third Block");
blockchain.addBlock(block2);
var block3 = blockchain.newBlock("Fourth Block");
blockchain.addBlock(block3);

console.log("Blockchain Validity: " + blockchain.isBlockchainValid());

blockchain.display();

var block4 = new Block(12, "falseHash", Date.now(), "Block Invalid");
blockchain.addBlock(block4);

console.log("Blockchain Validity: " + blockchain.isBlockchainValid());

blockchain.display();
