What is web.js?

Web3.js is a library that allows developers to interact with a blockchain from their JavaScript code

It is commonly used to access the Ethereum blockchain, but it can be used to interact with other blockchain networks as well

Web3.js provides methods for reading and writing data to the blockchain, as well as for listening to and responding to events on the blockchain

It is an important tool for developers who want to build decentralized applications (DApps) on the Ethereum platform.
