The new keyword in JavaScript can be quite confusing when it is first encountered, as people tend to think that JavaScript is not an object-oriented programming language. What is it? What problems ...
You should use new when you wish an object to remain in existence until you delete it. If you do not use new then the object will be destroyed when it goes out of scope.
Note, that when a function is called with the new keyword in javascript it exhibits special behavior. In your first statement the constructor function called is an already defined function, Function. As has been pointed out your first statement returns a function while the second returns an object.
A new expression is the whole phrase that begins with new. So what do you call just the "new" part of it? If it's wrong to call that the new operator, then we should not call "sizeof" the sizeof operator, or & the address-of operator (when it behaves like one).
new: if the keyword is used by a method, unlike override keyword, the reference type is important. If it is instantiated with derived class and the reference type is base class, the method of base class runs.
Note that if you declared it var a = new { }; and var o = new object();, then there is one difference, former is assignable only to another similar anonymous object, while latter being object, it can be assigned to anything.
