javascript - What is this variable type called? -

i looking though civclicker game code , found created variables little "sub variables" inside it. doesn't array me.

an example of variable initialization:

// initialise data var food = {     name:'food',     total:0,     increment:1,     specialchance:0.1 }, wood = {     name:'wood',     total:0,     increment:1,     specialchance:0.1 }, stone = {     name:'stone',     total:0,     increment:1,     specialchance:0.1 }, skins = {     name:'skins',     total:0, }, 

he later calls variables using:

food.total++; 

and on. if has information on type of variable greatful :)

these javascript objects. { .. } syntax known literal notation , 1 way of creating object. attributes between braces properties, or methods if value function.

the objects created using shorthand var syntax, same repeating var:

var = {}, b = {}; // same var = {}; var b = {}; 

there other ways of creating objects , setting properties, such as:

var food  = new object(); food.total = 0; food['name'] = 'food'; 

you can instantiate function create object, whereby function acts class.

function food {     this.total = 0;     this.name = ''; }  var f = new food(); f.total = 5; f.name = 'abc'; 

mdn working objects resource covers this.
