Understanding - What is JavaScript Object Prototyping/Prototypes

Показать описание
In this video we are going to be talking about - #JavaScript Object #Prototyping
#Prototype is an object that is associated with every functions and objects by default in JavaScript
Prototype property is accessible and modifiable and object's prototype property is not visible
Do all JavaScript objects have a prototype property?
Yes, Every JavaScript object has an internal "prototype" property, often called __proto__, which points to the object from which it directly inherits.
What is difference between __ proto __ and prototype?
__proto__ is an object in every class instance that points to the prototype it was created from.
In reality, the only true difference between prototype and __proto__ is that the former is a property of a class constructor, while the latter is a property of a class instance.
What is prototype chain?
Every object has a prototype, including the prototype object. This "chain" goes all the way back until it reaches an object that has no prototype, usually Object 's prototype.
Native prototypes
The "prototype" property is widely used by the core of JavaScript itself. All built-in constructor functions use it.
