Why I use "this" if I can...

Why I use "this" and I can assign the methods by function for example

var Portland = {
    bridges: 12,
    airport: 1,
    soccerTeams: 1,
    logNumberOfBridges: function() {
        console.log("There are " + Portland.bridges + " bridges in Portland!, and " + Portland.airport + " Airport")
    }
}

Portland.logNumberOfBridges();

Referring to itself by name inside an object can make your code "brittle" and subject to errors. Imagine, for example, if the following were added to the code above:

var city = Portland;
Portland = "not an object";
city.logNumberOfBridges();

But if "this" is used inside the object instead of "Portland", it would still work just fine.

Right, That makes sense. Thank you a lot, Steven.
