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.
