How to Use Function

Home Specialization Programs Help

Functions can be created using a "function" statement or the Function() constructor. Dynamic functions are created when defining functions with the "new" operator and Function() constructor. Constructors not only create new objects but also specify the behaviors and properties of those objects.

Function

The Function object provides methods for functions. In JavaScript, every function is actually a Function object.
