Objects, Javascript

Objects

//Objects

// Object Literal

var person = {
    firstName: 'Bird',
    lastName: 'Graves',
    age: 20,
    children: ['Max', 'Angel', 'Bosco'],
    address: {
        street: '555 something st',
        city: 'A City',
    state: 'AC' 
    },
    fullName: function(){
        return this.firstName +" "+this.lastName;
    }
}

//remember to check all your commas or you might be staring at the wrong section for 10 minutes wondering why its not working... *facepalm*

print(person.firstName);

var children = ['Max', 'Angel', 'Bosco']

children.forEach (function(child){
                 print(child);
})

// for full address:
print(person.address);

//it just shows up as 'object object", but thats alright.

//if you only want part of the address, eg: city, you put it after address:

print(person.address.city);

print(person.fullName());

//Object Constructor

//create a new object
var apple = new Object();
apple.color = 'red';
apple.shape = 'round';

//a function
apple.describe = function(){
    return 'An apple is the color '+this.color+' and is the shape '+this.shape+'.';
}

print(apple.describe());

//YAY it works!    
// dont forget- a function needs "()"!

// A simpler way to do this would be to use a Constructor Pattern.

//Constructor Pattern

function Fruit(name, color, shape){
    this.name = name;
    this.color = color;
    this.shape = shape;
    
    this.describe = function(){
    return 'A fruit that is '+this.color+' and '+this.shape+' is a '+this.name+'.';
    }
}
//create new fruit - all you have to do is this line instead of the whole thing for each fruit-
var pear = new Fruit('pear', 'green', 'round');

print(pear.describe());

// you can add arrays of objects

var users = [
    {
        name: 'John Doe',
        age: 30
    },
    {
        name: 'Macy Pacs',
        age: 23
    },
    {
        name: 'Josh Han',
        age: 63
    }
    ];
print(users[1].age);
