函数是 JavaScript 中的基本组件之一。JavaScript 中的函数类似于过程——一组执行任务或计算值的语句。但要成为函数,这个过程应该接受输入并返回与输入存在某些明显关系的输出。要使用一个函数,你必须将其定义在你希望调用它的作用域内。 参见JavaScript 函数的详细参考章节,以了解详情。
A traditional, old-browser-compliant solution is to simply save your reference tothisin a variable that can then be inherited by the closure, e.g.: Game.prototype.restart=function() {this.clearLocalStorage();constself =this;// Save reference to 'this', while it’s still this!this.timer=...

Sometimes this is not acceptable; many want their module to be an instance of some class. To do this, assign the desired export object to module.exports. Note that assigning the desired object to exports will simply rebind the local exports variable, which is probably not what you want to ...
