This tutorial will teach you the basics of web3.js, the JavaScript API for interacting with the Ethereum network. We’ll be building 2 scripts that will both accomplish the same thing: monitor transactions to a given Ethereum address. The first script is very slow and network and resource intensive, while the second is more elegant and less heavy on the network and system.
