Node.js Global Objects


Node.js worldwide items are worldwide in nature and accessible in all modules. You don't have to incorporate these items in your application; rather they can be utilized straightforwardly. These items are modules, capacities, strings and article and so on. A portion of these articles aren't very the worldwide extension yet in the module scope.
