JavaScript中的OOP，JavaScript对象属于什么类？

Question

From my basic understanding of Object Oriented Programming, a Class is a blueprint of an Object. For example, one might say apple, oranges etc is Object of Class Fruit.

I'm not understanding the structure , please forgive the basic-ness of this question.

When I look at the JavaScript Objects, for example a Date Object, or a Time Object..

What class for example does the Date Object belong to?

Answer 1

In Javascript, there is no concept of class as in case of other programming languages.

But, we can implement OOP in Javascript through prototypes .

Prototypes are a way through which we can define methods and properties in a function, which then can be inherited by objects created using the new keyword.

Answer 2

JavaScript does not use classical class-based inheritance, but prototyped inheritance. A Date object "inherits" from Date.prototype , which is the closest thing to the object you are looking for.
