A function factory is used to create function objects.

What is Function Factory?

We can have a function works as a factory which creates and returns function. We can return different functions based on parameter of function. As we have a function inside another function so closure is created and inner function will have access to function factory parameter even after it returns. This provides great flexibility for creation of functions.
