function(property, res, err, result){
var json = {};
json[property] = result;
res.json(json);
};
Okay, this is a function that will take the above parameters. When invoked it creates an Object called json, my question is about the next line I don’t understand it at all, is the object then the list of properties? Please enlighten me.
There are 2 ways to set the properties on objects. Most times people use dot notation like this:
json.property = result;
But if the property name is a string (which is what will be passed in as the property argument), the way the object property is set is like this:
json[property] = result
For example if someone puts these arguments into the function ("name", blah, blah, "Sam"), what is actually happening in the line in question is:
json["name"] = "Sam"
Which is equivalent to:
json.name = "Sam"
And results in an object named json that looks like this:
{
name: "Sam"
}
