object literal (字面模式)

var car = {
    horn: function() {
        alert("...");
    }
};
// ...
car.horn();

prototype (原型模式)

function car() {
    //
}

car.prototype.horn = function() {
    alert("...");
};

var camaro = new car();
camaro.horn();

singleton (单例模式)

var car = new function() {
    this.horn = function() {
        alert("...");
    };
};
// ...
car.horn();

object constructor (对象构造器)var car = new Object();
car.horn = function() {
alert("...");
};
// ...
car.horn();

function constructor (函数构造器)function car() {
    this.horn = function() {
        alert("...");
    };
}

var camaro = new car();
// ...
camaro.horn();

Object.create (IE 9+, FF 4+, Chrome 5+, Opera 11.6+, Safari 5+)

function car() {
    //
}

car.prototype = {
    horn: function() {
        alert("...");
    }
};

var camaro = Object.create(car.prototype);
// ...
camaro.horn();

待高手补充、、、

var obj = new object();
obj.name = '123';
var obj = {name:'123'};
var car = function(){};
var test = new car();
