1 00:00:02,130 --> 00:00:04,800 So we know that what you learn in this course 2 00:00:04,800 --> 00:00:08,270 will apply no matter which kind of code you'll write. 3 00:00:08,270 --> 00:00:11,320 But of course you might know that there are a lot 4 00:00:11,320 --> 00:00:13,520 of patterns and principles out there. 5 00:00:13,520 --> 00:00:17,150 Some specific for a specific programming language, 6 00:00:17,150 --> 00:00:20,220 some specific for a specific framework, 7 00:00:20,220 --> 00:00:24,340 and some specific to a specific programming paradigm. 8 00:00:24,340 --> 00:00:27,380 How are these patterns and principles then related 9 00:00:27,380 --> 00:00:29,650 to the idea of writing Clean Code? 10 00:00:29,650 --> 00:00:32,550 Should you always follow them all to ensure 11 00:00:32,550 --> 00:00:34,860 that you do write Clean Code? 12 00:00:34,860 --> 00:00:36,970 For this it is important to keep in mind 13 00:00:36,970 --> 00:00:39,090 that Clean Code is code 14 00:00:39,090 --> 00:00:42,010 which is readable and easy to understand. 15 00:00:42,010 --> 00:00:45,500 That is the main thing you have to keep in mind 16 00:00:45,500 --> 00:00:47,730 when writing Clean Code. 17 00:00:47,730 --> 00:00:49,634 Now all these patterns and principles out there 18 00:00:49,634 --> 00:00:53,260 are focused on ensuring that you write code 19 00:00:53,260 --> 00:00:55,970 which is extensible and maintainable. 20 00:00:55,970 --> 00:00:57,010 Of course, 21 00:00:57,010 --> 00:00:58,370 there is a connection. 22 00:00:58,370 --> 00:01:00,735 Of course if you follow these patterns and principles, 23 00:01:00,735 --> 00:01:03,510 that can help with writing Clean Code. 24 00:01:03,510 --> 00:01:05,030 On the other hand, 25 00:01:05,030 --> 00:01:07,270 if you name things poorly, 26 00:01:07,270 --> 00:01:09,820 if you format things poorly, 27 00:01:09,820 --> 00:01:12,560 if you have functions which are super clunky 28 00:01:12,560 --> 00:01:14,279 and messed up and hard to read, 29 00:01:14,279 --> 00:01:17,025 you can follow all these patterns and principles 30 00:01:17,025 --> 00:01:20,110 and you would still not have Clean Code. 31 00:01:20,110 --> 00:01:23,100 So this course really focuses on what makes up Clean Code, 32 00:01:23,100 --> 00:01:27,076 not on all possible patterns and principles you could learn. 33 00:01:27,076 --> 00:01:30,030 Of course there are some which matter a lot 34 00:01:30,030 --> 00:01:31,860 when it comes to writing Clean Code, 35 00:01:31,860 --> 00:01:33,975 and I will therefore cover them in the course, 36 00:01:33,975 --> 00:01:37,440 but some other principles are not as important 37 00:01:37,440 --> 00:01:40,080 from a Clean Code perspective. 38 00:01:40,080 --> 00:01:42,510 And there's one other differentiation I wanna dive in. 39 00:01:42,510 --> 00:01:46,470 And that would be Clean Code versus Clean Architecture. 40 00:01:46,470 --> 00:01:48,736 We can also make a differentiation here. 41 00:01:48,736 --> 00:01:51,076 Just as with the patterns and principles, 42 00:01:51,076 --> 00:01:53,930 of course there is a connection. 43 00:01:53,930 --> 00:01:57,900 But, Clean Code is really about writing guess what? 44 00:01:57,900 --> 00:01:58,733 Clean Code. 45 00:01:58,733 --> 00:02:00,880 It's about the code you write. 46 00:02:00,880 --> 00:02:02,730 Now a Clean Architecture 47 00:02:02,730 --> 00:02:06,200 is about how you structure your project, 48 00:02:06,200 --> 00:02:09,130 how you separate your entities, 49 00:02:09,130 --> 00:02:10,820 how you store your data. 50 00:02:10,820 --> 00:02:11,830 It's in the end, 51 00:02:11,830 --> 00:02:15,540 you could say where to write which code. 52 00:02:15,540 --> 00:02:18,039 Do you use dependency injection or not? 53 00:02:18,039 --> 00:02:21,330 These are questions you ask yourself 54 00:02:21,330 --> 00:02:24,110 when thinking about a Clean Architecture. 55 00:02:24,110 --> 00:02:26,800 And that's a different thing than Clean Code. 56 00:02:26,800 --> 00:02:29,343 and Clean Architecture also depends a lot on 57 00:02:29,343 --> 00:02:32,030 which programming paradigm you're following, 58 00:02:32,030 --> 00:02:35,450 and which programming language you're using. 59 00:02:35,450 --> 00:02:38,720 With Clean Code we focus on single code snippets. 60 00:02:38,720 --> 00:02:40,590 Single files you could say. 61 00:02:40,590 --> 00:02:43,740 With Clean Architecture we focus on the overall project 62 00:02:43,740 --> 00:02:45,340 and how to model our data 63 00:02:45,340 --> 00:02:47,410 and how to distribute our code. 64 00:02:47,410 --> 00:02:49,863 And this course therefore is about Clean Code. 65 00:02:49,863 --> 00:02:53,253 We'll not focus on things like the repository pattern 66 00:02:53,253 --> 00:02:54,980 or anything like that, 67 00:02:54,980 --> 00:02:57,914 because that is not really related to Clean Code. 68 00:02:57,914 --> 00:03:00,590 It doesn't matter where you access 69 00:03:00,590 --> 00:03:02,200 your database for example, 70 00:03:02,200 --> 00:03:03,963 from a Clean Code perspective. 71 00:03:03,963 --> 00:03:06,350 From a Clean Architecture perspective, 72 00:03:06,350 --> 00:03:07,470 that could matter, 73 00:03:07,470 --> 00:03:10,340 and you should therefore then take a dedicated course, 74 00:03:10,340 --> 00:03:13,120 if that is what you're primarily interested in. 75 00:03:13,120 --> 00:03:15,563 This course will focus on Clean Code.
