In this tutorial, you learned how to use Ethers.js with Infura to send Ether, interact with smart contracts, and deploy contracts on the Ethereum blockchain. This setup allows you to interact with the blockchain in real-time without the need to run your own Ethereum node, making it easier to develop decentralized applications (dApps) and other blockchain-based services.
Using Infura for node access and Ethers.js for transaction management and contract interaction gives you a powerful combination to build on Ethereum.
