How we can implement prototype-based inheritance?

Difficulty: 5/10

prototype chain, object creation, inheritance patterns

To implement prototype-based inheritance in JavaScript, you essentially link one object to another so that the second object can delegate property lookups to the first.

1
Object.create() is the most direct way to implement prototypal inheritance. It creates a new object and allows you to specify exactly which object should be its prototype.
2
You can create a prototype-based inheritance by defining methods and properties on a prototype object and then using a constructor function to create instances that inherit from that prototype. This allows you to define shared behaviour that is available to all instances of the object.
3
Classes make the prototype-based implementation much easier to read. Even though it looks like 'Class-based' code, JavaScript is still just setting up a prototype chain behind the scenes.
