And in fact, that's, 65 65 00:03:12,690 --> 00:03:16,100 what's so special about a single wait. 66 66 00:03:16,100 --> 00:03:19,990 So it's the fact that it makes our code look like regular 67 67 00:03:19,990 --> 00:03:23,000 synchronous code while behind the scenes. 68 68 00:03:23,000 --> 00:03:26,690 Everything is in fact asynchronous. 69 69 00:03:26,690 --> 00:03:28,190 All right. 70 70 00:03:28,190 --> 00:03:33,190 But anyway, as soon as this premise here is resolved, 71 71 00:03:33,240 --> 00:03:36,600 then the value of this whole await expression that we have 72 72 00:03:36,600 --> 00:03:41,200 here is going to be the resolved value of the premise. 73 73 00:03:41,200 --> 00:03:44,583 And so we can simply store that into a variable. 74 74 00:03:46,290 --> 00:03:48,560 So let's call it res 75 75 00:03:48,560 --> 00:03:50,640 for response. 76 76 00:03:50,640 --> 00:03:54,820 And then here we can take a look at that response. 77 77 00:03:54,820 --> 00:03:58,570 And just to show you that this function here is actually 78 78 00:03:58,570 --> 00:04:00,120 asynchronous. 79 79 00:04:00,120 --> 00:04:03,163 Let's log something to the console before we call it. 80 80 00:04:05,230 --> 00:04:09,770 So just first, because this should be printed first, right? 81 81 00:04:09,770 --> 00:04:12,570 And then, or actually we should call the function first. 82 82 00:04:13,660 --> 00:04:15,210 So where am I 83 83 00:04:15,210 --> 00:04:16,043 with 84 84 00:04:17,090 --> 00:04:18,410 Portugal? 85 85 00:04:18,410 --> 00:04:19,903 But even by doing this, 86 86 00:04:21,060 --> 00:04:24,540 this console dot log first will be displayed first, 87 87 00:04:24,540 --> 00:04:27,380 because again, this is an a sync function. 88 88 00:04:27,380 --> 00:04:29,590 And so once the function is called, 89 89 00:04:29,590 --> 00:04:32,450 it is then loaded off to the background. 90 90 00:04:32,450 --> 00:04:35,770 And so this Fetcher will be running in the background 91 91 00:04:35,770 --> 00:04:37,890 without blocking or main threat. 92 92 00:04:37,890 --> 00:04:40,600 And so the code will move on to the next line, 93 93 00:04:40,600 --> 00:04:43,363 which is then this console dot log first. 94 94 00:04:44,500 --> 00:04:46,070 All right. 95 95 00:04:46,070 --> 00:04:47,660 And so 96 96 00:04:47,660 --> 00:04:49,790 indeed we got the first 97 97 00:04:49,790 --> 00:04:51,310 printed first 98 98 00:04:51,310 --> 00:04:52,143 and then here, 99 99 00:04:52,143 --> 00:04:54,140 we got the response, 100 100 00:04:54,140 --> 00:04:58,160 but this time we got this response in this really nice and 101 101 00:04:58,160 --> 00:04:59,173 elegant way. 102 102 00:05:00,110 --> 00:05:03,630 So you see here that by using a sync await 103 103 00:05:03,630 --> 00:05:04,790 or asynchronous 104 104 00:05:04,790 --> 00:05:06,020 code here, Oh, 105 105 00:05:06,020 --> 00:05:09,800 really looks and feels like synchronous code. 106 106 00:05:09,800 --> 00:05:13,930 So we can simply await until the value of the premise is 107 107 00:05:13,930 --> 00:05:15,730 returned basically. 108 108 00:05:15,730 --> 00:05:19,880 And then just assign that value to a variable meant that is 109 109 00:05:19,880 --> 00:05:22,470 something that was impossible before. 110 110 00:05:22,470 --> 00:05:26,210 So before we had to mess with callback functions and dead 111 111 00:05:26,210 --> 00:05:28,020 was true in callback hell, 112 112 00:05:28,020 --> 00:05:31,800 but also by consuming premises with the then method. 113 113 00:05:31,800 --> 00:05:35,870 But now with a sync await, that is just completely gone, 114 114 00:05:35,870 --> 00:05:37,090 right? So again, 115 115 00:05:37,090 --> 00:05:40,920 this looks now like normal synchronous code where we simply 116 116 00:05:40,920 --> 00:05:43,570 assign values to a variable, 117 117 00:05:43,570 --> 00:05:47,090 and that makes it so much easier and more clean. 118 118 00:05:47,090 --> 00:05:48,870 In my opinion. 119 119 00:05:48,870 --> 00:05:51,490 Now, before you start using a sync await all 120 120 00:05:51,490 --> 00:05:52,690 over the place, 121 121 00:05:52,690 --> 00:05:57,070 you need to first understand that a sink await is in fact, 122 122 00:05:57,070 --> 00:06:01,980 simply syntactic sugar over the then method in premises. 123 123 00:06:01,980 --> 00:06:06,080 So of course behind the scenes, we are still using premises. 124 124 00:06:06,080 --> 00:06:10,540 We are simply using a different way of consuming them here 125 125 00:06:10,540 --> 00:06:13,730 in this case, but what we have here. 126 126 00:06:13,730 --> 00:06:17,240 So this is essentially exactly the same 127 127 00:06:17,240 --> 00:06:18,073 as doing 128 128 00:06:18,990 --> 00:06:20,080 it the old way, 129 129 00:06:20,080 --> 00:06:21,220 basically. 130 130 00:06:21,220 --> 00:06:23,080 So using then and then res 131 131 00:06:24,680 --> 00:06:26,850 and then console dot log res 132 132 00:06:27,830 --> 00:06:28,803 like we did here. 133 133 00:06:29,860 --> 00:06:31,863 So this is exactly the same. 134 134 00:06:34,080 --> 00:06:35,280 So let's put that here 135 135 00:06:37,290 --> 00:06:38,940 and 136 136 00:06:38,940 --> 00:06:40,320 comment it out of course, 137 137 00:06:40,320 --> 00:06:43,770 because what we are interested in is indeed a sync await 138 138 00:06:43,770 --> 00:06:44,603 right now. 139 139 00:06:45,690 --> 00:06:48,960 So now that we know how a sync await works, 140 140 00:06:48,960 --> 00:06:52,720 it's time to actually recreate the, where am I a function? 141 141 00:06:52,720 --> 00:06:55,410 So first off we need to get the Jason 142 142 00:06:55,410 --> 00:06:56,243 out 143 143 00:06:56,243 --> 00:06:58,770 of this response, 144 144 00:06:58,770 --> 00:07:00,110 right? 145 145 00:07:00,110 --> 00:07:02,330 And so remember on the response, 146 146 00:07:02,330 --> 00:07:03,640 we need to call 147 147 00:07:03,640 --> 00:07:05,250 Jason 148 148 00:07:05,250 --> 00:07:07,760 and remember that this itself returns 149 149 00:07:07,760 --> 00:07:09,100 a new premise. 150 150 00:07:09,100 --> 00:07:12,400 And so previously we would have to return this premise 151 151 00:07:12,400 --> 00:07:15,020 and then chain another then handler. 152 152 00:07:15,020 --> 00:07:17,392 But now this becomes so much easier. 153 153 00:07:17,392 --> 00:07:19,480 All we have to do is to, again, 154 154 00:07:19,480 --> 00:07:22,050 await this and then we can store 155 155 00:07:22,050 --> 00:07:24,620 the results directly into the data 156 156 00:07:24,620 --> 00:07:27,113 variable that we have been using before. 157 157 00:07:30,160 --> 00:07:31,070 Right? 158 158 00:07:31,070 --> 00:07:33,280 And so here it is. 159 159 00:07:33,280 --> 00:07:35,619 So here is the same data as before. 160 160 00:07:35,619 --> 00:07:38,203 And so now all we need to do is to render it. 161 161 00:07:39,480 --> 00:07:40,800 So render country 162 162 00:07:41,650 --> 00:07:43,380 and data 163 163 00:07:43,380 --> 00:07:45,080 at position zero, 164 164 00:07:45,080 --> 00:07:48,810 and in case you skipped any of the previous videos and don't 165 165 00:07:48,810 --> 00:07:51,773 have this render country function, for some reason, 166 166 00:07:51,773 --> 00:07:56,390 you can simply get it from the final files of the section, 167 167 00:07:56,390 --> 00:07:58,310 from the getup repository. 168 168 00:07:58,310 --> 00:08:03,310 So from where you also got the starter files now, okay. 169 169 00:08:03,410 --> 00:08:04,340 And 170 170 00:08:04,340 --> 00:08:05,350 yeah, 171 171 00:08:05,350 --> 00:08:06,760 there is our data 172 172 00:08:06,760 --> 00:08:07,840 so render it 173 173 00:08:07,840 --> 00:08:09,760 to the page here. 174 174 00:08:09,760 --> 00:08:10,600 Great. 175 175 00:08:10,600 --> 00:08:15,600 And all without de-chaining of premises like we had before. 176 176 00:08:15,830 --> 00:08:18,440 So this is really elegant.
