Removing all properties from a object

Question

I have this Javascript object.

req.session 

In my code I add properties to this object. These properties can be other objects, arrays, or just plain strings.

req.session.savedDoc = someObject;  req.session.errors = ['someThing', 'anotherThing', 'thirdThing']; req.session.message = 'someString' 

If I later would like to erase all added properties of this object, what is the easiest/best way?

There must be a better way than this?

// Delete all session values delete req.session.savedDoc; delete req.session.errors; delete req.session.message;

@VisioN's answer works if you want to clear that specific reference, but if you actually want to clear an object I found that this works:

for (var variableKey in vartoClear){     if (vartoClear.hasOwnProperty(variableKey)){         delete vartoClear[variableKey];     } }
