I am able to run a code like this
myObject.save(function(error, data){
if(error){
console.log(error);
}
else {
console.log(data);
}
});
What i don't understand is where the anonymous function get the arguments error and data from?
Its from the thing that calls it - so save might look like this:
function save(callback) {
//do stuff
var error = false;
var data = {
something: 'horse'
};
callback(error, data)
}
There's no magic going on - its just a function call
