WEBVTT 00:00.000 --> 00:02.490 -: In this video, we're gonna talk about the capabilities 00:02.490 --> 00:05.185 and limitations of using GitHub Copilot. 00:05.185 --> 00:07.560 GitHub Copilot is able to generate efficient, 00:07.560 --> 00:11.550 high-quality code from both comments and function names. 00:11.550 --> 00:12.383 As well as that, 00:12.383 --> 00:15.780 it's also able to generate high-quality code suggestions. 00:15.780 --> 00:17.910 And the reason for this is GitHub Copilot 00:17.910 --> 00:21.600 is constantly adapting to your project source code 00:21.600 --> 00:24.393 and therefore adapting to your coding style 00:24.393 --> 00:26.520 and project that you're working on. 00:26.520 --> 00:28.290 So if you're coding in JavaScript, 00:28.290 --> 00:30.390 GitHub Copilot will start parsing 00:30.390 --> 00:32.640 and understanding your JavaScript files. 00:32.640 --> 00:34.440 And if you're coding in another language, 00:34.440 --> 00:36.990 it will understand those files, 00:36.990 --> 00:38.880 and therefore the types of responses 00:38.880 --> 00:40.470 that you get back from GitHub Copilot 00:40.470 --> 00:42.240 are incredibly personalized. 00:42.240 --> 00:44.670 You can also choose from multiple suggestions, 00:44.670 --> 00:47.910 so if you're unhappy with the suggestion you see, 00:47.910 --> 00:51.330 it's possible to toggle through multiple suggestions 00:51.330 --> 00:54.270 until you find a suggestion that you like. 00:54.270 --> 00:56.430 Let's explore some of the limitations. 00:56.430 --> 00:59.760 Personally, I found that if I'm trying to generate code, 00:59.760 --> 01:04.050 or learn about code in a very extensive and long way, 01:04.050 --> 01:08.370 I found that ChatGPT will provide more extensive codes 01:08.370 --> 01:09.960 than GitHub Copilot. 01:09.960 --> 01:13.050 However, GitHub Copilot really shines 01:13.050 --> 01:16.140 when you're looking to just stay in the flow of coding, 01:16.140 --> 01:18.660 and you know roughly how to solve the problem, 01:18.660 --> 01:21.180 and you just want a couple of tips along the way. 01:21.180 --> 01:23.640 That's a really great use case for GitHub Copilot. 01:23.640 --> 01:26.370 Also, it's worth noting that GitHub Copilot 01:26.370 --> 01:28.590 can be slower in larger projects. 01:28.590 --> 01:31.830 The reason for this is that as your project size grows, 01:31.830 --> 01:33.390 there are more source files 01:33.390 --> 01:35.910 that GitHub Copilot needs to parse. 01:35.910 --> 01:37.380 And so this can also be something 01:37.380 --> 01:39.030 that's a slight limitation. 01:39.030 --> 01:41.910 Another point to add is the limited configurability 01:41.910 --> 01:43.410 of GitHub Copilot. 01:43.410 --> 01:46.410 Because there aren't any model operations or options, 01:46.410 --> 01:49.470 there's no way we can really influence GitHub Copilot, 01:49.470 --> 01:51.180 apart from doing the following. 01:51.180 --> 01:53.610 We can provide it with more extensive comments. 01:53.610 --> 01:56.619 We can also use different function/class names. 01:56.619 --> 01:59.010 We also have the variability 01:59.010 --> 02:02.520 as to what existing source coding is within the product. 02:02.520 --> 02:05.370 And also adding types to your code is a really great way 02:05.370 --> 02:07.620 of helping GitHub Copilot to understand 02:07.620 --> 02:09.480 what the different types of information 02:09.480 --> 02:10.920 such as variables are. 02:10.920 --> 02:13.350 As well as that, you can also try using a different package. 02:13.350 --> 02:16.410 So newer packages are less likely to be stable 02:16.410 --> 02:20.880 with GitHub Copilot, whilst older, more maintained packages, 02:20.880 --> 02:24.180 there's more likely to be more training data inside 02:24.180 --> 02:27.780 of the large language model to support effective generation 02:27.780 --> 02:30.000 and suggestions for those older packages. 02:30.000 --> 02:31.440 So that's also something to consider. 02:31.440 --> 02:32.940 The other thing that's worth mentioning 02:32.940 --> 02:35.670 is that GitHub Copilot is not a free tool, 02:35.670 --> 02:37.170 and you would have to pay for it. 02:37.170 --> 02:38.003 In the next video, 02:38.003 --> 02:40.410 we'll look at how to install GitHub Copilot 02:40.410 --> 02:41.853 inside of your VS Code.
