兼容AMD,nodejs/commonjs规范的模块定义-读knockoutjs源码
//闭包执行一个立即定义的匿名函数
! function (factory) {
//factory是一个函数，下面的koExports就是他的参数
// Support three module loading scenarios
if (typeof require === 'function' && typeof exports === 'object' && typeof module === 'object') {
// [1] CommonJS/Node.js
// [1] 支持在module.exports.abc,或者直接exports.abc
var target = module['exports'] || exports; // module.exports is for Node.js
factory(target);
