1 00:00:00,560 --> 00:00:01,970 In this video. 2 00:00:02,000 --> 00:00:10,750 Let's talk about string concatenation, meaning how can we combine two or more strings together? 3 00:00:10,760 --> 00:00:13,700 And that's what you call string concatenation. 4 00:00:13,700 --> 00:00:18,530 So let me comment out all these ones for future references. 5 00:00:18,530 --> 00:00:21,020 And now let's begin a new concept. 6 00:00:21,110 --> 00:00:22,580 So we're down here. 7 00:00:22,820 --> 00:00:27,050 Down here, let's comment here and you have this comment that is a new topic. 8 00:00:27,050 --> 00:00:28,790 So string. 9 00:00:31,440 --> 00:00:32,700 Concatenation. 10 00:00:34,510 --> 00:00:39,070 We have couple of ways of combining strings together. 11 00:00:39,100 --> 00:00:43,150 The first one is using the plus operator. 12 00:00:44,390 --> 00:00:47,570 So let's see, how can we combine strains together? 13 00:00:47,600 --> 00:00:56,390 So let's say that I have this two counts and I would need my first string and string one which is equal 14 00:00:56,390 --> 00:00:57,950 to hello. 15 00:00:59,150 --> 00:01:02,000 And now next one going to be string. 16 00:01:02,000 --> 00:01:05,630 Going to be string two is equal to. 17 00:01:08,230 --> 00:01:09,520 How are you? 18 00:01:11,210 --> 00:01:11,660 Perfect. 19 00:01:11,660 --> 00:01:15,490 So for these two strains, how can I combine them together? 20 00:01:15,500 --> 00:01:19,360 And that's what you call concatenation for the plus operator. 21 00:01:19,370 --> 00:01:21,140 Let's see how we are going to do it. 22 00:01:21,140 --> 00:01:29,030 So as usual, let me assign the result into a variable called result equal to I would take the string 23 00:01:29,030 --> 00:01:35,540 one which represents hello and then I would add plus string two together. 24 00:01:35,750 --> 00:01:36,530 Perfect. 25 00:01:36,530 --> 00:01:43,550 So down here if I try to console.log the results here, let's see. 26 00:01:43,550 --> 00:01:46,250 We see that I have something happening here. 27 00:01:46,370 --> 00:01:47,840 Hello, how are you? 28 00:01:47,900 --> 00:01:54,920 We see that the first one, which is string one, is this particular. 29 00:01:54,920 --> 00:01:55,490 Hello. 30 00:01:55,850 --> 00:02:03,230 And then the string two, which is how are you is from here and this one and you can see that there 31 00:02:03,230 --> 00:02:04,970 is no space between them. 32 00:02:05,150 --> 00:02:11,150 So to do that, we're going to add some space between the hello and how are you. 33 00:02:11,180 --> 00:02:16,070 So this how you're going to do so after this one. 34 00:02:16,100 --> 00:02:23,120 After this, you're going to add additional double quotes space and then plus. 35 00:02:23,390 --> 00:02:26,930 So if I save it now something has happened. 36 00:02:26,930 --> 00:02:27,590 We have. 37 00:02:27,590 --> 00:02:29,420 Hello, how are you? 38 00:02:29,420 --> 00:02:30,630 So that's how we are. 39 00:02:30,650 --> 00:02:34,760 We can we can contact or combine string together. 40 00:02:35,030 --> 00:02:40,970 And then you also have one method using the contact method from JavaScript. 41 00:02:41,000 --> 00:02:42,500 So the same process. 42 00:02:42,500 --> 00:02:44,240 So let me comment out here. 43 00:02:44,330 --> 00:02:44,930 Okay. 44 00:02:45,080 --> 00:02:49,100 The next method is using the contact method. 45 00:02:49,580 --> 00:02:50,540 Contact. 46 00:02:51,550 --> 00:02:52,420 Mitt it. 47 00:02:53,190 --> 00:02:54,540 Like that. 48 00:02:54,930 --> 00:02:56,700 So how are we going to do it? 49 00:02:56,700 --> 00:02:57,710 So the same thing. 50 00:02:57,720 --> 00:02:59,730 So let me bring this one here. 51 00:03:00,150 --> 00:03:02,160 Copy it and then paste it here. 52 00:03:02,190 --> 00:03:03,820 This one is for operator here. 53 00:03:03,840 --> 00:03:07,260 So let me comment this one out like that. 54 00:03:07,260 --> 00:03:11,310 And now how can we contact this strength together? 55 00:03:11,740 --> 00:03:18,360 Okay, so I remove this one and then I'll bring in the first string. 56 00:03:18,390 --> 00:03:21,000 That is string number one, which is this one. 57 00:03:21,060 --> 00:03:24,630 And on that, I have a method called coin cat. 58 00:03:25,060 --> 00:03:25,670 Perfect. 59 00:03:25,680 --> 00:03:28,710 So before you move on, let me show you some tricks here. 60 00:03:29,340 --> 00:03:38,820 Anything that comes after DOT is either a method or a property of that particular variable that you 61 00:03:38,820 --> 00:03:40,260 want to work on. 62 00:03:40,560 --> 00:03:48,120 So we see that as soon as I type dot, the code is giving me some options that which methods do you 63 00:03:48,120 --> 00:03:48,910 want to use? 64 00:03:48,930 --> 00:03:56,900 And we have a bunch of them and I'll work you through most of these methods with some coding challenges. 65 00:03:56,910 --> 00:04:00,480 So for the meantime, let's stick to contact. 66 00:04:00,960 --> 00:04:06,830 So contact takes in some elements that you need to pass into this. 67 00:04:06,840 --> 00:04:11,610 So I want to contact meaning add string number two into that. 68 00:04:11,700 --> 00:04:19,529 So if I save it, if we see that I have as before, but you can see that there is no space between them 69 00:04:19,529 --> 00:04:20,029 here. 70 00:04:20,040 --> 00:04:29,460 So to add a space, you bring space here like that, you bring your double code space and then add plus 71 00:04:29,460 --> 00:04:29,840 here. 72 00:04:29,850 --> 00:04:35,850 So with this one, if I save it, you see that now everything is perfect as before. 73 00:04:35,860 --> 00:04:42,060 So that is about the string concatenation, how we can combine string together. 74 00:04:42,090 --> 00:04:43,820 This is really crucial. 75 00:04:43,830 --> 00:04:47,190 You need to pay attention how to combine string together. 76 00:04:47,220 --> 00:04:52,560 The next video we will talk about what is called JavaScript template literal.
