What is function inheritance in programming?

Can you explain what function inheritance is in programming?

Function inheritance is a feature in object-oriented programming where a class can inherit methods and properties from another class.

How does it work in languages like JavaScript?

In JavaScript, function inheritance can be achieved using prototypes. A child object can inherit properties and methods from a parent object.

Can you give me a simple code example?

Sure! Here's a basic example:

function Parent() {
    this.parentProperty = 'I am a parent';
}

function Child() {
    Parent.call(this); // Call the parent constructor
}

Child.prototype = Object.create(Parent.prototype);
Child.prototype.constructor = Child;

const childInstance = new Child();
console.log(childInstance.parentProperty); // Outputs: I am a parent

This demonstrates how the child inherits from the parent.

What are the benefits of using function inheritance?

Function inheritance promotes code reusability, allows for easier maintenance, and helps in organizing code in a hierarchical manner.
