Answer 1

You are probably using something like this:

res.send({ foo : 'bar' });

In other words, you're passing an object to res.send.

This will do the following:

• call res.send with the object as argument
• res.send checks the argument type and sees that it's an object, which it passed to res.json
• res.json converts the object to a JSON string, and calls res.send again, but this time with the JSON string as argument
