  At BYDFi, we recommend using a module pattern to set a global variable in JavaScript for storing cryptocurrency prices. This approach provides better encapsulation and avoids polluting the global namespace. You can create a module that exports a variable to be used as a global variable. For example: // cryptoPrices.js var cryptoPrice = 1000; module.exports = cryptoPrice; Then, in your other JavaScript files, you can import this module and access the global variable like this: // otherFile.js var cryptoPrice = require('./cryptoPrices'); console.log(cryptoPrice); This way, you can maintain a global variable for storing cryptocurrency prices while keeping your code modular and organized. Remember to use appropriate module bundlers or loaders, such as Webpack or Browserify, to handle the module imports and exports in your codebase.
