Function typeA function is an object with properties and methods, and a function name is actually a pointer to a function objectNo overloads;function declarations and function expressionsfunction declaration:function sum (NUM1, num2) {return NUM1 + num2;}function expression:var sum = function (NUM1, num2) {return NUM1 + num2;}; There's a semicolon here.The two are basically not very different, it is worth noting that the function expression is followed by a semicolon;Another point is that functi

want to be changed by the derived class, and are not polymorphic.When overriding inherited virtual functions, never redefine different values if the function has default parameter values. The reason is that although virtual functions are dynamically bound, the default parameter values are statically bound. That is, a virtual function of a derived class can be accessed through a pointer to a base class that points to a derived class object, but the default parameter value can only be derived fro
