This crash course teaches you how to build decentralized applications using Web3.js and smart contracts on the Ethereum network. It is designed for beginners who want to understand how blockchain applications connect front-end code with smart contracts.
You will start by learning what Web3.js is and how it allows JavaScript applications to communicate with the Ethereum blockchain. The course then introduces smart contracts and explains how they are created, deployed, and used inside real blockchain applications.
You will also explore how Ethereum transactions work, including how data is sent, stored, and processed on the blockchain. The course explains how to deploy smart contracts and interact with them using Web3.js in practical examples.
In addition, you will learn about smart contract events, which allow applications to respond to blockchain activity in real time. You will also understand how to inspect blocks and transactions to better analyze blockchain data.
By the end of this crash course, you will be able to connect JavaScript applications to Ethereum smart contracts and build basic decentralized applications, giving you a strong foundation in Web3 development and blockchain integration.
