What are JavaScript prototypes?
JavaScript prototypes are objects from which other objects inherit properties. They are a fundamental part of JavaScript's object-oriented programming.
How do prototypes work in JavaScript?
Prototypes work by allowing objects to share methods and properties. When you create an object, it has a prototype that can be accessed via the __proto__
property.
Can you give me an example of using prototypes?
Sure! If you have a constructor function Person
, you can add methods to Person.prototype
, and all instances of Person
will have access to those methods.
What is the difference between prototype and instance properties?
Prototype properties are shared among all instances, while instance properties are unique to each object created from the constructor.
