How to instanciate a view ?

Hi,

It seems there are several ways to instanciate a view! What's the difference between 

var oView =  sap.ui.view({id:"parent", viewName:"parent", type:sap.ui.core.mvc.ViewType.JS});

var oView = new sap.ui.view({id:"parent", viewName:"parent", type:sap.ui.core.mvc.ViewType.JS});

Thanks
