Listing 9.01 - Adding methods to our constructed object - Tasks 1&2

Create a second planet. Use the buildPlanet function.
Call the showPlanet method on your new planet.


var buildPlanet = function (name, position, type) {
    var planet = {};

    planet.name = name;
    planet.position = position;
    planet.type = type;

    planet.showPlanet = function () {
        var info = planet.name;
        info += ": planet " + planet.position;
        info += " - " + planet.type;
        console.log(info);
    };

    return planet;
};

var planet1 = buildPlanet(
    "Jupiter",
    5,
    "Gas Giant"
);

// build a second planet
var planet2 = buildPlanet(
    "Neptune",
    8,
    "Ice Giant"
);

planet1.showPlanet();

// display the new planet
planet2.showPlanet();
