oop - What javascript object pattern is this example using? -

i'm making javascript/canvas game , saw example on css tricks. here's link http://css-tricks.com/9876-learn-canvas-snake-game/#comment-100804

anyways, i'm wondering because i'm refactoring game code, , creating own objects , far looks pattern using.

to me, looks revealing module pattern read on http://addyosmani.com/resources/essentialjsdesignpatterns/book/

so right?

/* note: snippet example, go link see finished example */   var js_snake = {};  js_snake.game = (function () {   var ctx;   js_snake.width = 200;   js_snake.height = 200;   js_snake.blocksize = 10;   var framelength = 500; //new frame every 0.5 seconds   var snake;    function init() {     $('body').append('<canvas id="jssnake">');     var $canvas = $('#jssnake');     $canvas.attr('width', js_snake.width);     $canvas.attr('height', js_snake.height);     var canvas = $canvas[0];     ctx = canvas.getcontext('2d');     snake = js_snake.snake();     bindevents();     gameloop();   }    function gameloop() {     ctx.clearrect(0, 0, js_snake.width, js_snake.height);     snake.advance();     snake.draw(ctx);     settimeout(gameloop, framelength); //do again   }    function bindevents() {     var keystodirections = {       37: 'left',       38: 'up',       39: 'right',       40: 'down'     };      $(document).keydown(function (event) {       var key = event.which;       var direction = keystodirections[key];        if (direction) {         snake.setdirection(direction);         event.preventdefault();       }     });   }    return {     init: init   }; })(); 

also, there better pattern should using when creating objects in javascript/canvas game?

if check out game, go website. http://magnut.comze.com

the game created called fruit blitz , next update i'm working on right going big one, enemies, power ups , such.

it's instantiated function (iif) returns object 1 method. creates js_snake.game.init method can use assigned within iif closure. i don't know if has has specific pattern name.. it's known module pattern.

see this so-question immediate function invocation

from raynos' answer i'd borrow: a lot of these "patterns" (they aren't patterns) personal preferences.

you may interested in reading more prototype pattern - base of javascript - this may start.
