JavaScript Prototype Inheritance with IIFE in ES5

I try demonstrate inheritance with immediately invokable function expression(IIFE) and prototype in the following code.

This sample code is written in different concepts you should read the following posts as well.

The following code demonstrate classic inheritance with JavaScript.

Same code as shown in the above, but I added a new function named inherit in global Function.prototype so that we don't need to write same code for inheritance. It looks like Employee.inherits(Person); or Manager.inherits(Employee);

Notice that although Employee and Manager functions doesn't have inherits function, it works due to global Function.prototype.inherits
