 //Object literal
var john = {
    firstName : 'John',
    lastName : 'Smith',
    birthYear : 1990,
    family : ['Jane', 'Mark', 'Bob', 'Emily'],
    job : 'teacher',
    isMarried : false
}

console.log(john.firstName);
console.log(john['lastName']);	//이런 식으로 접근하는 것도 가능하다.

var x = 'birthYear';
console.log(john['birthYear']);

john.job = 'designer';
console.log(john['job']);

john['isMarried'] = true;
console.log(john.isMarried);

// new Object syntax
var jane = new Object();
jane.firstName = "Jane";
jane.birthYear = 1969;
jane['lastName'] = 'Smith'
console.log(jane);

오브젝트 안에 메소드를 정의할 수도 있다. 

var mark = {
    firstName : "Mark",
    lastName : "mark",
    mass : 70,
    height : 1.75,
    BMICalc : function(){
        return this.mass / (this.height * this.height);
    }
}
