The snake code looks very similar to this tutorial[1].

Tutorial: //Get the directions document.onkeydown = function(e) { var key = e.keyCode; //console.log(key);

			if(key == 37 && dir != "right") setTimeout(function() {dir = "left"; }, 30);
			else if(key == 38 && dir != "down") setTimeout(function() {dir = "up"; }, 30);
			else if(key == 39 && dir != "left") setTimeout(function() {dir = "right"; }, 30);
			else if(key == 40 && dir != "up") setTimeout(function() {dir = "down"; }, 30);

			if(key) e.preventDefault();

		}

Jennifer's code: $(document).on('keydown', function (e) { var key = e.keyCode;

		if (key == 37 && snake.dir != 'right') {
			setTimeout(function () {
				snake.dir = 'left';
			}, 30);
		} else if (key == 38 && snake.dir != 'down') {
			setTimeout(function () {
				snake.dir = 'up';
			}, 30);
		} else if (key == 39 && snake.dir != 'left') {
			setTimeout(function () {
				snake.dir = 'right';
			}, 30);
		} else if (key == 40 && snake.dir != 'up') {
			setTimeout(function () {
				snake.dir = 'down';
			}, 30);
		}

		e.preventDefault();
