  To declare and use global variables in JavaScript, you can simply declare them outside of any function or block. For example: var globalVariable = 'some value'; Then, you can access this variable from any part of your JavaScript code. However, it's generally recommended to minimize the use of global variables to avoid potential conflicts and maintain code clarity. Consider using local variables or encapsulating your code in modules or classes instead.
