Why is it not necessary for the first callback to return the body?

I was kind of expecting the on('data') callback function to have to return the body variable for it to be able to work in the next one. Wouldn't that be normal JavaScript behavior? Are things different in node.js?

Because the body is a variable defined inside the http.get callback so when is treated inside the function it is actually affecting that variable and now that variable is full of information taken from the 'data' event callback.
