两者之间有什么区别吗？

function MyFunc() {
    // code...
}

和

var MyFunc = function() {

        body: null,
        canvas: null,
        context: null,
        grids: [],

        interval: null,
        control: null,

        tableBack: null,

        init: function(width, height) {
            gol.body = document.getElementsByTagName('body')[0];
            gol.canvas = document.createElement('canvas');
            if (gol.canvas.getContext) {
                gol.context = gol.canvas.getContext('2d');
                document.getElementById('content').appendChild(gol.canvas);
                gol.canvas.width = width;
                gol.canvas.height = height;
                gol.canvas.style.marginLeft = "8px";

                gol.control = document.getElementById('gridcontrol');

                gol.canvas.onmousedown = gol.onMouseDown;
                gol.canvas.onmousemove = gol.onMouseMove;
                gol.canvas.onmouseup …
