  When it comes to cryptocurrency programming with JavaScript, there are several global variables that developers often utilize. One of the most commonly used global variables is 'web3', which is a JavaScript library that allows developers to interact with the Ethereum blockchain. 'web3' provides access to various functions and properties that enable developers to send transactions, read smart contract data, and interact with decentralized applications (DApps). Another important global variable is 'eth', which represents the Ethereum blockchain itself. Developers can use 'eth' to access blockchain data, such as block information, transaction details, and account balances. These global variables play a crucial role in the functionality and security of cryptocurrency applications, as they provide the necessary tools and interfaces for developers to interact with the blockchain and ensure the proper execution of transactions and smart contracts.
