1 00:00:00,180 --> 00:00:00,670 Beautiful. 2 00:00:01,200 --> 00:00:06,150 And once we understand the global in note, I want to talk about the module's. 3 00:00:06,750 --> 00:00:14,450 And first, let's return to this command post we have here, Noad and Pajares. 4 00:00:15,320 --> 00:00:24,050 And probably the question that you have is, well, does that mean that all my application needs to 5 00:00:24,050 --> 00:00:25,070 be in this one file? 6 00:00:25,960 --> 00:00:28,570 And the answer, again, is yes and no. 7 00:00:29,020 --> 00:00:34,990 Yes, you'll execute one file, but you'll split your code in modules. 8 00:00:34,990 --> 00:00:41,320 Otherwise that would be literally insane to jump all your code in one file. 9 00:00:41,710 --> 00:00:48,160 Effectively, I'll just show you with an extremely complex app and of course, extremely complex in 10 00:00:48,160 --> 00:00:49,270 the air right now. 11 00:00:49,630 --> 00:00:53,860 And you'll see why I would want to use the modules in the first place. 12 00:00:53,890 --> 00:00:58,570 So next video, I'll give you official intro with a bunch of gibberish and all that. 13 00:00:58,570 --> 00:01:05,260 But for the time being, let's just build a super complex app and then see why you would want to use 14 00:01:05,260 --> 00:01:07,770 those modules in the first place. 15 00:01:08,020 --> 00:01:15,550 And if you have any familiarity with six modules, if you have worked with them in vanilla jars or in 16 00:01:15,550 --> 00:01:17,920 reactors, you already in good shape. 17 00:01:18,340 --> 00:01:22,900 The syntax is going to be tiny bit different because, you know, it uses common commentary's. 18 00:01:23,230 --> 00:01:25,530 But the general idea is exactly the same. 19 00:01:25,960 --> 00:01:31,600 And we start with a simple function by the name of say hi, you guessed it. 20 00:01:31,870 --> 00:01:37,540 And this function is going to be looking for the name, parameter and line inside of the function. 21 00:01:37,550 --> 00:01:38,270 What do we do? 22 00:01:38,680 --> 00:01:46,470 We simply consult a log and we say hello there and then whatever is the name of the dude or the gal 23 00:01:46,480 --> 00:01:48,010 that is being passed. 24 00:01:48,010 --> 00:01:50,130 And as a parameter, we're going to invoke it. 25 00:01:50,140 --> 00:01:51,430 And I can say say hi. 26 00:01:51,430 --> 00:01:57,820 And then passing, Suzanne, for example, in order to make this interesting, I'll set up some variables 27 00:01:57,820 --> 00:01:58,360 as well. 28 00:01:58,780 --> 00:02:01,480 So I'm going to say cons, John is equal to John. 29 00:02:02,400 --> 00:02:08,590 And you guessed it, since there is a gene that also has to be Apiata, and hopefully you get the gist. 30 00:02:09,090 --> 00:02:14,670 So imagine we would have a bunch of names and then we have probably more functions than this one. 31 00:02:14,670 --> 00:02:18,480 But for the time being, this is just going to be say how we copy and paste. 32 00:02:18,480 --> 00:02:26,760 We invoke this function, I guess, three times, one for Johnny boy, one for Peter, and the first 33 00:02:26,760 --> 00:02:28,160 one we already have for Susan. 34 00:02:28,560 --> 00:02:29,420 And what do we do? 35 00:02:29,430 --> 00:02:32,480 We run no more Appoggiaturas. 36 00:02:32,850 --> 00:02:33,590 We're on that. 37 00:02:33,600 --> 00:02:35,810 And there is in Arkansas, we can clearly see. 38 00:02:35,850 --> 00:02:37,490 Hello there, Susan, blah, blah, blah. 39 00:02:37,890 --> 00:02:46,110 Now, wouldn't it make sense if the names would be separate as well as this function or the future functions 40 00:02:46,410 --> 00:02:53,160 that we're going to create would be in separate files and then we can access them all throughout the 41 00:02:53,190 --> 00:02:53,940 application. 42 00:02:54,270 --> 00:03:00,600 And that way you would have smaller files and more structure to our application. 43 00:03:00,810 --> 00:03:04,650 And that is exactly what the modules allow us to do. 44 00:03:04,980 --> 00:03:09,630 And that's why we'll move on and start talking about the modules in the next video.
