  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.

  Ah, global variables in cryptocurrency programming with JavaScript! They're like the secret sauce that makes everything work smoothly. One of the most popular global variables in this realm is 'web3'. It's like the Swiss Army knife of Ethereum development, giving you access to all sorts of goodies. With 'web3', you can send transactions, read smart contract data, and even build your own decentralized applications (DApps). Another global variable you'll often come across is 'eth'. It represents the Ethereum blockchain itself, and with it, you can dive deep into the blockchain's data, exploring blocks, transactions, and account balances. These global variables are the backbone of cryptocurrency applications, providing the necessary tools and interfaces for developers to create secure and functional solutions.
