一个debugger就知道了this.__proto__ === ko.constructor.prototype;this.__proto__ === AppViewModel.prototype; 有用 回复 Even_Yu 1.4k634 发布于 2018-06-22 兄弟那个函数叫自执行函数 格式为(function(){})()这是一般格式 现在有es6了 所以也可以写成: (()=>{})()箭头函数。 至于你说的有关...

console.log(fn.proto.constructor === Function); varfn=newFunction("console.log(123456);");// Function是用来构建函数的.console.log(fn);fn();// // 在没有修改过原型链的情况下. 以下等式是成立的.// console.log(fn.__proto__.constructor === Function.prototype.constructor);// console.log(...
The Prototype parameter is the name of this prototype function.Function Specifies the function being called. This can be the name of the function (preferably qualified with a module name), or any other expression that evaluates to the function address. If you need to call a constructor or ...

The debugger of course will take you in the right path, but it may become a bit more difficult to decide where to put your breakpoints. As for easier to make mistakes. In some cases, a virtual function shall not call its base implementation, in some it shall call it at the beginning ...
V1053. Calling the 'foo' virtual function in the constructor/destructor may lead to unexpected result at runtime. V1054. Object slicing. Derived class object was copied to the base class object. V1055. The 'sizeof' expression returns the size of the container type, not the number of eleme...
