I remember interviewing Tencent interns when the interviewer asked me such a question. Copy Code code as follows: What is the difference between the two statements below? function foo () {}; var bar = function foo () {};

virtual functions are defined in the base class for overload and polymorphism, and can be overridden or not written in a base class, even if the definition is null. pure virtual functions are not defined in the base class and must be implemented in

JavaScript is an interpreted language, and function declarations are interpreted after the JavaScript code is loaded and executed, and the function expression is interpreted only when it executes to this line of code.There are two ways to define a
