00:00:00,180 --> 00:00:01,110
Welcome back.

2
00:00:01,350 --> 00:00:05,400
In this video we'll be recapping what we've learned in the past couple of videos.

3
00:00:05,550 --> 00:00:10,530
We learned that object oriented programming is a model based on objects which are constructed from some

4
00:00:10,530 --> 00:00:17,130
kind of blueprint in languages that had built in support for O.P. we call these blueprints classes and

5
00:00:17,130 --> 00:00:23,190
the objects created from them instances since we do not have built in class support in javascript.

6
00:00:23,190 --> 00:00:29,130
We mimic the functionality of classes by using functions to create objects through the use of constructor

7
00:00:29,130 --> 00:00:31,220
functions and the new keyword.

8
00:00:31,380 --> 00:00:36,540
We also saw that the new keyword does four things creates an object out of thin air.

9
00:00:36,570 --> 00:00:43,420
It sets the value of the keyword this to be that object created in the previous step it adds or return

10
00:00:43,440 --> 00:00:45,490
this to the constructor function.

11
00:00:45,660 --> 00:00:51,720
And finally it sets a property on the object which we can access called Dunder Prato.

12
00:00:51,930 --> 00:00:55,230
We'll talk much more about that in the next video.

13
00:00:55,270 --> 00:01:02,040
Finally we can refactor duplication if multiple constructor functions share properties by invoking another

14
00:01:02,040 --> 00:01:08,310
constructor function and using call or apply to set the value of the keyword this to be the correct

15
00:01:08,400 --> 00:01:12,960
object created from the constructor function in the next video.

16
00:01:12,990 --> 00:01:18,320
We'll examine a property on functions called prototype and dive even deeper into what the new keyword

17
00:01:18,330 --> 00:01:19,170
does.

18
00:01:19,230 --> 00:01:19,990
