Does NodeJS have equivalent to web browser window object?

In NodeJS there is not available window object equivalent like in web browsers, but there is global object that represents global scope inside module.

In browsers, the top-level scope is the global scope. This means that within the browser var something will define a new global variable. In Node.js this is different. The top-level scope is not the global scope; var something inside a Node.js module will be local to that module.
