1 00:00:02,530 --> 00:00:06,400 Let me show you how I'm going to solve this particular challenge. 2 00:00:06,490 --> 00:00:12,640 The first one is going to be pretty simple because the functions we take in, let's say a string and 3 00:00:12,640 --> 00:00:18,760 then repeat it many times, meaning the number of repetitions is going to be fixed by the string we 4 00:00:18,760 --> 00:00:21,190 pass in is going to be dynamic. 5 00:00:21,430 --> 00:00:23,350 So solution number one. 6 00:00:24,080 --> 00:00:27,770 Solution one let's go second. 7 00:00:27,800 --> 00:00:31,760 Let's say KONST hasn't enough room here. 8 00:00:32,659 --> 00:00:36,980 KONST Let me call it as repeat. 9 00:00:38,080 --> 00:00:39,640 Repeat string. 10 00:00:40,970 --> 00:00:52,130 And now it's eco to function parentheses, carry bases, retain the functions you take in a string str 11 00:00:52,160 --> 00:00:59,180 and then on that, on the string I can use repeat, then I won't repeat, let's say five times or ten 12 00:00:59,180 --> 00:01:04,700 times depending how you want it, or 20 times, let's say six times that is it. 13 00:01:04,700 --> 00:01:15,230 So if I assign the result coming back from calling the function as repeat string or let me string g 14 00:01:15,230 --> 00:01:21,770 here g so here I'll passing the string I want to repeat, let me encode as Node.js. 15 00:01:23,340 --> 00:01:24,240 Node.js. 16 00:01:24,480 --> 00:01:28,170 So let's check the result here. 17 00:01:29,350 --> 00:01:31,920 You see, that has repeated many times. 18 00:01:32,160 --> 00:01:32,850 Perfect. 19 00:01:33,000 --> 00:01:41,790 So the next question is that here the next question is going to be improved upon this one for this one, 20 00:01:41,810 --> 00:01:44,700 because if you pass in a fixed value here. 21 00:01:44,910 --> 00:01:50,790 But the next challenge is that we are going to make this one also dynamic, and then you're going to 22 00:01:50,790 --> 00:01:53,570 check if a is a pass in, let's say a string. 23 00:01:53,580 --> 00:01:59,730 Let's say that for this function I didn't pass anything and see that when I check for the results, 24 00:02:00,450 --> 00:02:03,150 you see that I get empty string and I don't want that. 25 00:02:03,150 --> 00:02:07,600 I want to check if a user didn't provide in, let's say a string. 26 00:02:07,600 --> 00:02:11,220 Instead I place the character must be less than zero. 27 00:02:11,970 --> 00:02:13,460 Okay, good. 28 00:02:13,470 --> 00:02:15,060 Much more than zero. 29 00:02:15,060 --> 00:02:15,540 Yeah. 30 00:02:15,630 --> 00:02:23,190 So that's how the that's how this I mean, the first challenge is sorry about so I can copy this one. 31 00:02:24,820 --> 00:02:25,890 Okay. 32 00:02:25,900 --> 00:02:27,280 And then come down here. 33 00:02:27,310 --> 00:02:33,910 I solution too so here would name it as repeat string to that is it. 34 00:02:34,060 --> 00:02:36,780 So inside here things are going to be changed. 35 00:02:36,790 --> 00:02:44,070 So this function takes in what it says that the function should take to activate the string and a number. 36 00:02:44,080 --> 00:02:48,340 So I'm going to pass in the number of times I want to repeat this. 37 00:02:48,580 --> 00:02:55,690 So here I'll pass in second parameter here as num number and here return what. 38 00:02:56,900 --> 00:03:08,120 Retain string, my string dots repeats repeat, then I'll pass in the number of times I want to repeat. 39 00:03:08,420 --> 00:03:09,110 That is it. 40 00:03:10,490 --> 00:03:11,020 That is it. 41 00:03:11,030 --> 00:03:11,930 But you. 42 00:03:11,960 --> 00:03:13,450 You're going to improve a little bit. 43 00:03:13,460 --> 00:03:20,900 So let's assign the result coming back as my answer is equal to repeat two, then I'll pass in. 44 00:03:20,930 --> 00:03:26,150 First of all, let's say hello, then I won't repeat this 190 times. 45 00:03:26,510 --> 00:03:34,010 So if I check my console for answer, we see that it has repeated I mean 90 times here, but let's say 46 00:03:34,010 --> 00:03:35,050 I didn't provide anything. 47 00:03:35,120 --> 00:03:37,550 Let's say zero empty string that I didn't get. 48 00:03:37,550 --> 00:03:40,310 Let me check that I'm going to have empty string. 49 00:03:40,310 --> 00:03:47,570 So let's check if I didn't provide if the length or character is a pass and it's less than zero. 50 00:03:47,810 --> 00:03:49,130 So let's check. 51 00:03:49,820 --> 00:03:54,200 Check if the number. 52 00:03:55,960 --> 00:03:59,590 Of character is the let me say the the length. 53 00:04:01,360 --> 00:04:02,740 Of this training. 54 00:04:06,160 --> 00:04:10,930 Is less than or equal to. 55 00:04:13,500 --> 00:04:14,070 Zero. 56 00:04:14,220 --> 00:04:14,790 So. 57 00:04:14,790 --> 00:04:15,690 So here, let's check. 58 00:04:15,700 --> 00:04:16,390 So, Eve. 59 00:04:16,410 --> 00:04:17,959 Remember, you talk about lamb. 60 00:04:18,000 --> 00:04:19,860 Is that how crucial it is right now? 61 00:04:20,130 --> 00:04:21,899 So let's say that. 62 00:04:22,500 --> 00:04:25,410 Well, let's check for the number, not the string. 63 00:04:25,410 --> 00:04:25,740 Sorry. 64 00:04:25,740 --> 00:04:31,560 So then if the number is less than or equal to zero, then we can return. 65 00:04:31,560 --> 00:04:37,820 Remember for written keyword, any time you use a return key word keyword and the condition parses is 66 00:04:37,830 --> 00:04:41,040 going to exit the entire function. 67 00:04:41,040 --> 00:04:43,260 So here we see that number. 68 00:04:44,960 --> 00:04:46,610 Must be. 69 00:04:48,410 --> 00:04:49,340 Greater than. 70 00:04:50,000 --> 00:04:51,680 Greater than. 71 00:04:52,710 --> 00:04:53,310 Zero. 72 00:04:54,120 --> 00:04:57,030 I think check if the number so if the number. 73 00:04:57,810 --> 00:05:03,240 So if the numbers are here how checking for the string if the number is less than zero. 74 00:05:03,240 --> 00:05:04,140 So here. 75 00:05:05,820 --> 00:05:11,400 Let's provide let's say, I mean, come has my strength. 76 00:05:11,400 --> 00:05:17,700 And then if I provide this one, let me check let me check inside my console and see let me check for 77 00:05:17,700 --> 00:05:18,320 the enzyme. 78 00:05:18,330 --> 00:05:23,970 See that I get it as 90 times I can, let's say 9000 times. 79 00:05:24,210 --> 00:05:26,790 Let me check with the function. 80 00:05:26,790 --> 00:05:29,460 See that I have to click more before I can see the rest. 81 00:05:29,460 --> 00:05:32,790 See that I repeat it 9000 times. 82 00:05:32,820 --> 00:05:35,280 That's how function is crazy know in programming. 83 00:05:35,550 --> 00:05:38,010 So let's say that I didn't provide. 84 00:05:38,010 --> 00:05:39,480 I probably say zero here. 85 00:05:40,710 --> 00:05:42,150 Let me check for the answer. 86 00:05:42,180 --> 00:05:45,090 You see, that place number might be greater than zero. 87 00:05:45,300 --> 00:05:46,290 So if I. 88 00:05:46,320 --> 00:05:47,370 Let's see one. 89 00:05:48,270 --> 00:05:51,050 You're going to repeat what all you want times. 90 00:05:51,060 --> 00:05:54,220 So let's check for the answer and see that come. 91 00:05:54,240 --> 00:05:56,610 I can repeat ten times. 92 00:05:57,370 --> 00:05:58,120 Let's check. 93 00:05:58,240 --> 00:05:59,920 Yes, that is it.
