?//?其實這一部分是用來判斷jQ運行環境的，第一運行環境是node.js類似CommonJS和CommonJ，第二個環境是window，就是客戶端，（瀏覽器）

里面說過：(function(global, factory) {
??? factory(global);
}(typeof window !== "undefined" ? window : this, function(window, noGlobal) {
??? var jQuery = function( selector, context ) {
?? ??? ?return new jQuery.fn.init( selector, context );等價于

(function(global) {
? ? var factory=function(global, undenfined) {
??? ????var jQuery = function( selector, context ) {
?? ??? ?????return new jQuery.fn.init( selector, context );

????????????}

????????}
})(typeof window !== "undefined" ? window : this);

factory參數傳入的是個function，就是后面括號里的function(window, noGlobal) window=global，noglobal可看作undenfined未定義
