Thanks! great explanation.

Jut one question related to twitter example:

T.get('search/tweets', params, function(err, data, response) {
if(!err){
// This is where the magic will happen
} else {
console.log(err);
}
})

I do understand we’ve passed a callback function as third argument; in this callback function, we have passed three arguments, so questions are:

  1. How do we know we need to pass three arguments?
  2. How do we know first argument would be error…and so on?
  3. How T.get(), high-order function, will pass response to callback function…?
