if is one of the longest judgments in all programming languages, what exactly can be used in the if Chinese as a judgment expression in JS? For example, how many lines, just a few parentheses, true and false is completely different, what does it mean? var obj={}; Obj. Funtext=function () {}; if (obj. Funtext) { alert ("True

functions of constructor are analyzed. The Code is as follows: Script// Define a functionVar f = function (){}// True is displayed here, because the f constructor is Funtion, and the prototype attribute _ proto _ in f is assigned as the prototype of the constructor, that is, Function prototype.// Instanceof checks whether the _ proto _ in f has a common node with Function. prototype. If yes, true is returned.Alert (f instanceof Function)// Obj is

hasOwnProperty: is used to determine whether an object has a property or object that you give a name to, and this method cannot check whether the object has that property in its prototype chain, and that property must be a member of the object itself.isPrototypeOf is used to determine whether the object whose prototype chain is to be checked exists in the specified object instance, or True, otherwise returns false.The instanceof action checks whether the object is named property. You can also ch
