Is exports an object returned from module.exports

If I have this hello.js file:

var greeting = function() {
    console.log('Hello');
}

module.exports = greeting;

Then in main.js:

var temp = require('./hello.js');
temp();

When you say module.exports = greeting is that attaching the greeting function to the exports object on module. Since when I require hello.js in main.js I am able to call temp() directly. And don't have to do like temp.greeting();

Does this mean that since require returns module.exports it just returning the method on the exports object rather than returning the exports object entirely correct? I am confused on why it is returning what is on the exports object (the greeting function) and not the real exports object itself.

require(...) returns module.exports from that module. This is usually an object, but it can also be anything else (usually a function) like in your case where the module exports only a single function.

There's nothing wrong with doing this - module.exports is just a plain object (there's most likely something like module.exports = {}; somewhere in the code that runs "around" the contents of a module's js file)
