1 00:00:00,640 --> 00:00:01,480 This video. 2 00:00:01,480 --> 00:00:07,360 Let's talk about the last method and that is the object dot entries. 3 00:00:08,080 --> 00:00:10,480 Let's have some enough room to code. 4 00:00:10,810 --> 00:00:13,060 So let me copy this one. 5 00:00:13,840 --> 00:00:16,180 And then let me comment this one out. 6 00:00:16,300 --> 00:00:17,290 Now come down. 7 00:00:17,290 --> 00:00:23,350 Here it and here is going to be my objects. 8 00:00:23,350 --> 00:00:25,570 Dot entries. 9 00:00:26,920 --> 00:00:28,340 So what is it? 10 00:00:28,360 --> 00:00:39,970 Well, the object dot entries method, it retains an array where each array contains a key and the value. 11 00:00:40,450 --> 00:00:45,100 Well, this is really useful when you want to treat over the properties of an object. 12 00:00:45,190 --> 00:00:46,420 Well, so let's see. 13 00:00:46,720 --> 00:00:50,620 Let's in action to better understand this definition I gave you. 14 00:00:50,680 --> 00:00:51,740 So const. 15 00:00:51,940 --> 00:01:04,780 Let's say my object entries now is is entries is equal to object uppercase dot entries. 16 00:01:04,810 --> 00:01:09,160 Then I'll pass in my person object. 17 00:01:10,100 --> 00:01:10,880 How is that? 18 00:01:11,180 --> 00:01:18,020 So if I console that look, my object entries have a look. 19 00:01:20,150 --> 00:01:20,540 Okay. 20 00:01:20,570 --> 00:01:21,120 Open it. 21 00:01:21,140 --> 00:01:21,910 We see that. 22 00:01:22,690 --> 00:01:28,030 It has put in the individual properties in a separate array. 23 00:01:28,420 --> 00:01:31,350 So let me show you that the first one is first name. 24 00:01:31,360 --> 00:01:33,330 So that the first one give me array. 25 00:01:33,340 --> 00:01:37,450 We have the first name, the key and the value is John. 26 00:01:37,570 --> 00:01:40,620 The next property was last name and then my value. 27 00:01:41,020 --> 00:01:44,530 They have put everything in a separate word array. 28 00:01:44,890 --> 00:01:50,350 So there are some useful there are some use cases where you may need this concept. 29 00:01:50,680 --> 00:01:58,300 Well, so for this one, we can go ahead and also maybe we can use for loop to loop through this element 30 00:01:58,300 --> 00:02:00,130 and get the individual entries. 31 00:02:00,730 --> 00:02:07,930 Or let's use for loop, let's use for a loop to see how we can loop through this one and you see how 32 00:02:07,930 --> 00:02:09,520 you're going to get the result. 33 00:02:09,789 --> 00:02:16,030 So here I'm going to have the object entries dot for each loop. 34 00:02:16,940 --> 00:02:21,230 For each loop pass in my callback function. 35 00:02:21,500 --> 00:02:27,770 And now here I get access to the individual entry and then my carry basis. 36 00:02:28,100 --> 00:02:31,490 So here, our console log the entry. 37 00:02:33,800 --> 00:02:37,400 Let's see now and see that I get it as before. 38 00:02:37,400 --> 00:02:45,520 But now I have them separately inside my for each loop and you cause something destruction assignment 39 00:02:45,530 --> 00:02:47,060 so the same way. 40 00:02:47,420 --> 00:02:48,830 So here it is advanced. 41 00:02:48,860 --> 00:02:49,630 Don't worry. 42 00:02:49,640 --> 00:02:54,380 The whole idea is get know how to use these entries and how. 43 00:02:54,380 --> 00:02:58,670 And I mean the meaning of these entry method and how they are used. 44 00:02:58,700 --> 00:03:03,890 As we move on and by solving some coding challenges, you better understand them in some way. 45 00:03:03,890 --> 00:03:04,760 Use cases. 46 00:03:05,060 --> 00:03:10,250 So here, what I'm going to do is I'm going to use a method called distraction assignment. 47 00:03:10,700 --> 00:03:11,450 Let me show you. 48 00:03:13,430 --> 00:03:15,080 Destruction assignment. 49 00:03:18,440 --> 00:03:19,160 So let's see. 50 00:03:19,160 --> 00:03:25,610 I would take my entries, my assets, my object, and let me comment this one out. 51 00:03:25,610 --> 00:03:26,950 So this one is reason for loop. 52 00:03:26,970 --> 00:03:35,030 Okay, so I would take my object entries, object entries and then dot for each the same way. 53 00:03:35,780 --> 00:03:39,680 Dot for each, for each. 54 00:03:39,680 --> 00:03:45,170 Then my callback function I'll start and then I'll start. 55 00:03:45,410 --> 00:03:49,880 But inside my callback function I'm going to structure this. 56 00:03:49,880 --> 00:03:52,520 Also a new feature in Java code instruction. 57 00:03:52,670 --> 00:03:54,650 For the meantime, just bear with me. 58 00:03:54,860 --> 00:04:00,860 Remember that this entries retains array of key value pairs. 59 00:04:00,890 --> 00:04:01,790 Let me show you here. 60 00:04:01,910 --> 00:04:08,930 So if our comment this one out, let's see we see that we have the key and a value. 61 00:04:08,930 --> 00:04:16,490 So this once represent the individual entry inside this function I'm going to have so I can structure 62 00:04:16,490 --> 00:04:20,180 that using a mean square bracket. 63 00:04:20,180 --> 00:04:22,790 So inside my callback function. 64 00:04:24,450 --> 00:04:25,050 Here. 65 00:04:25,320 --> 00:04:27,180 Now I can do structure. 66 00:04:27,780 --> 00:04:29,370 And then the first key. 67 00:04:29,370 --> 00:04:32,910 The first one is my key and comma, my value. 68 00:04:33,330 --> 00:04:40,200 So in here I can console.log it and give it some nice details and say that, well, I'm going to have 69 00:04:40,200 --> 00:04:48,420 my my temporarily try here dollar sign carry basis and then I have my key, my key here inside that 70 00:04:48,420 --> 00:04:54,270 and then I'm going to have semicolon and then I'll have my dollar sign, curly braces and my value. 71 00:04:55,620 --> 00:04:57,510 So let me comment this one. 72 00:04:57,600 --> 00:05:00,900 I want to see the results of this one and now have a look. 73 00:05:01,410 --> 00:05:09,510 We see I get first name John, last name double H like that and like that. 74 00:05:09,510 --> 00:05:13,650 Like I said, there are some use cases where you may need this concept. 75 00:05:13,680 --> 00:05:17,070 Not always you may need, but in some use cases. 76 00:05:17,070 --> 00:05:24,570 Well, guys, so here ends the object basics even though it is not business but high C is a basic right 77 00:05:24,870 --> 00:05:28,260 because advance I'm going to make things more complicated. 78 00:05:28,260 --> 00:05:33,210 I mean by I then I mean advanced object to a method, right? 79 00:05:33,210 --> 00:05:37,260 So the next video, let's start with our first coding challenge.
