nodejs global

The global object in Node.js represents the global scope in a Node.js application. When a variable is declared in Node.js without the var, let, or const keyword, it becomes a property of the global object. This makes it accessible throughout the application. However, it is recommended to explicitly declare variables using var, let, or const to avoid polluting the global scope and potential naming conflicts. The global object also provides access to global objects and functions, such as console and process, without the need to require them explicitly. It is important to use the global object judiciously to avoid unintended consequences in the application.
