Sample Code: Interacting with the Ethereum Blockchain using Web3.js

Here’s an example of how to use Web3.js to interact with the Ethereum blockchain:

const Web3 = require('web3');
const web3 = new Web3(new Web3.providers.HttpProvider('https://mainnet.infura.io/v3/YOUR_PROJECT_ID'));

// Get the current block number
web3.eth.getBlockNumber().then((blockNumber) => {
    console.log(`Current block number: ${blockNumber}`);
});

// Get the balance of an Ethereum account
web3.eth.getBalance('0x742d35Cc6634C0532925a3b844Bc454e4438f44e').then((balance) => {
    console.log(`Balance: ${balance}`);
});

This code snippet demonstrates how to use Web3.js to get the current block number and the balance of an Ethereum account.
