Operator overloading provides a flexibility option for creating new definitions of C++ operators. There are some C++ operators which we can't overload. The lists of such operators are: Class ... Moreover, arguments.callee substantially hinders optimizations like inlining functions, because it must be made possible to provide a reference to the un-inlined function if arguments.callee is accessed. arguments.callee for strict mode functions is a non-deletable property which throws when set or retrieved.

Function overloading in Javascript: Function overloading is the ability of a programming language to create multiple functions of the same name with different implementations. when an overloaded function is called it will run function a specific implementation of that function appropriate to the context of the call.

Overloading is the technique to use a single identifier to define various methods or techniques of a class that differs in their input and output parameters. The concept of overloading is generally used when a program block conceptually executes the same task but with a slight distinctness in a set of parameters.

CPP Function Overriding with example program code : Function overriding in CPP is the process of defining same function as defined in its base class in order to achieve runtime polymorphism. The advantage of using function overriding is that it provides the ability for specific implementation of the function, already provided by its base class.
