1 00:00:00,500 --> 00:00:06,470 This lesson, we're going to be exploring the JavaScript object method and looking at how objects work 2 00:00:06,470 --> 00:00:12,620 and what arrays are and how we can output the value of an object to an array and some more information 3 00:00:12,620 --> 00:00:18,710 about in general about objects so you can run functions that are contained within objects. 4 00:00:18,960 --> 00:00:23,950 So as you can see in this example, we're returning back a value for the person first. 5 00:00:23,960 --> 00:00:24,800 So we're turning back. 6 00:00:24,820 --> 00:00:30,260 Hello and whatever the value of person first is, and we can also update these objects. 7 00:00:30,590 --> 00:00:34,810 So now the challenge in this lesson is to take what we did earlier. 8 00:00:34,820 --> 00:00:40,340 So if you used a car and if you haven't used a car, you can grab one of the car objects that we have 9 00:00:40,340 --> 00:00:48,170 before and add in methods that we can invoke with JavaScript, that we can turn the car on and drive 10 00:00:48,290 --> 00:00:53,810 and then output the messages as those actions are being taken place into the console. 11 00:00:53,930 --> 00:00:58,610 I'll give you a quick sneak peek how to do this and you can pause the video. 12 00:00:58,610 --> 00:01:01,010 I'll walk you through the solution coming up. 13 00:01:01,400 --> 00:01:04,960 Well, let's set up our car object some values. 14 00:01:04,970 --> 00:01:08,590 We've got color of red and come a separate those out. 15 00:01:08,600 --> 00:01:16,100 So maybe we have a top speed for this car and that can be three hundred and 300 miles, 300 kilometers. 16 00:01:16,340 --> 00:01:18,440 Not quite sure at this point what it is. 17 00:01:18,840 --> 00:01:20,620 Let's give it model. 18 00:01:20,630 --> 00:01:24,710 So this can be a Mustang since it sounds like it's going to go super fast. 19 00:01:25,070 --> 00:01:30,590 Give it another value here so you can add as many as necessary here. 20 00:01:30,710 --> 00:01:32,300 And this is just a combination. 21 00:01:32,310 --> 00:01:36,080 So we've got no we've got some strings. 22 00:01:36,410 --> 00:01:38,390 And let's also add in one more number. 23 00:01:38,400 --> 00:01:41,210 So we've got a price value for the car. 24 00:01:41,630 --> 00:01:44,810 And now let's go to adding in the methods. 25 00:01:45,030 --> 00:01:52,240 So we wanted to add in a method where we do something such as turn it on and then this can equal a function. 26 00:01:52,580 --> 00:01:54,380 We're not going to take in any parameters. 27 00:01:54,590 --> 00:02:02,390 We're going to consider log out that this car is start it looks add in one more where we've got drive 28 00:02:03,080 --> 00:02:09,040 again, creating the function, the anonymous function and then outputting into the console. 29 00:02:09,050 --> 00:02:15,500 Let's console log that you are driving and now we are ready to try this. 30 00:02:15,500 --> 00:02:17,900 So go and go into your console. 31 00:02:18,360 --> 00:02:21,830 You can see within my car all the values that we have available to us. 32 00:02:22,040 --> 00:02:29,630 So if we do my car and we do drive invoking the function, we're running the block of code and we're 33 00:02:29,630 --> 00:02:32,060 being returned back that you are driving. 34 00:02:32,510 --> 00:02:38,630 Also, maybe we want to take some information that's contained within this object so we can reference 35 00:02:38,630 --> 00:02:41,440 the information from the object itself. 36 00:02:41,450 --> 00:02:43,100 I'm going to just concatenate it together. 37 00:02:43,100 --> 00:02:49,040 So if we want it to this, if we do the my car, you Mustang driving. 38 00:02:49,040 --> 00:02:55,190 So it's taking the information and notice as well that we can use this in order to reference the current 39 00:02:55,940 --> 00:02:56,660 object. 40 00:02:56,870 --> 00:03:01,610 So instead of doing the my car dot model, we can use this DOT model. 41 00:03:01,760 --> 00:03:06,590 So this also provides us some more flexibility when we're writing out our code and we're creating our 42 00:03:06,590 --> 00:03:06,920 code. 43 00:03:06,920 --> 00:03:12,350 And before we conclude, there's actually one other way that we can have methods in here and then to 44 00:03:12,350 --> 00:03:16,100 consider log, but we can do it within this format as well. 45 00:03:16,100 --> 00:03:21,530 So if we list out the value of my car, you're going to see at the end we've got one called works. 46 00:03:21,530 --> 00:03:22,490 This is a function. 47 00:03:22,700 --> 00:03:29,090 So it understands that this is a function and I can do my car works and invoke the function and we can 48 00:03:29,090 --> 00:03:31,310 see that that block a code gets run as well. 49 00:03:31,520 --> 00:03:32,930 So that's another option. 50 00:03:33,170 --> 00:03:37,730 But typically, I do like to do this type of format where we've got the anonymous function and then 51 00:03:37,730 --> 00:03:40,580 we've got the block, a code that's being run in between there.
