WEBVTT 00:01.290 --> 00:07.710 I hope that you have done this just correctly or at least try to find a solution or make it find even 00:07.710 --> 00:09.120 a better solution for our task. 00:09.510 --> 00:12.010 But anyway, let's go ahead and do it step by step. 00:12.900 --> 00:17.090 So the first step was to create an array students instead. 00:17.100 --> 00:22.920 There are four items, which should be objects and have three properties, name square ones, Corto 00:23.430 --> 00:32.130 with the following values so right for students and pass the items as objects. 00:32.670 --> 00:37.680 We need to open curly braces and that create the properties name. 00:38.920 --> 00:39.340 John. 00:41.100 --> 00:42.540 Then score one. 00:44.560 --> 00:45.500 Forty seven. 00:47.070 --> 00:48.210 And score to. 00:49.950 --> 00:50.510 To six. 00:54.030 --> 00:56.850 Let's copy it and paste three times. 01:00.040 --> 01:01.810 We don't need this Colma here. 01:03.190 --> 01:06.730 And also change the values right here, Bob. 01:08.450 --> 01:13.100 And this course as twenty three and twenty four. 01:15.460 --> 01:16.480 Then, Nick. 01:18.550 --> 01:22.900 With course 40 and 35. 01:25.600 --> 01:27.310 Elder law student Alex. 01:29.810 --> 01:34.010 Change this course, you're right, 44 and 45. 01:35.330 --> 01:36.950 All right, the first up is done. 01:37.100 --> 01:38.540 The next is also very simple. 01:38.540 --> 01:43.160 One, we just need to create two arrays for scores and degrees. 01:43.640 --> 01:44.350 Let's do it. 01:44.360 --> 01:45.740 Create variables cause. 01:47.020 --> 01:47.530 And. 01:48.850 --> 01:54.220 Let's place here as items the passing limit's 91 81. 01:56.030 --> 01:56.360 One. 01:57.500 --> 01:59.900 61 and 51. 02:01.940 --> 02:04.970 Then create variable degrees and. 02:06.420 --> 02:07.020 Insert. 02:08.890 --> 02:09.550 Items. 02:11.910 --> 02:14.070 A, B, c. 02:16.000 --> 02:16.990 The anti. 02:17.980 --> 02:24.880 OK, let's see what is the next step we need to create function which will calculate total score for 02:24.880 --> 02:25.430 each student. 02:26.030 --> 02:27.760 It's also the very simple step. 02:28.120 --> 02:32.230 So create function and call it calculate some. 02:34.190 --> 02:40.990 This function will receive two parameters for score one and score two, so let's place them in kind 02:41.000 --> 02:41.630 of short way. 02:43.470 --> 02:51.710 Then inside the braces create new variable sum and assign to score one plus score to. 02:54.450 --> 02:57.960 And then in order to get the value some, we have to return it. 03:01.560 --> 03:06.120 All right, I'm sure that you didn't have any trouble to come to this point. 03:06.540 --> 03:09.890 Now it's time to start the main and more interesting part of this test. 03:10.590 --> 03:12.300 So we need to create a function. 03:12.300 --> 03:18.300 And using this function, we need to figure out which student has passed an exam and what kind of degree 03:18.300 --> 03:19.590 of diploma he has got. 03:20.130 --> 03:24.240 So creates new function and call it calculates final. 03:28.510 --> 03:34.420 In order to see the results and also test the codes that we are going to write, let's call this function 03:35.050 --> 03:36.940 right below the name of this function. 03:38.680 --> 03:44.240 As you have just seen, we have created the general function for calculating the total score of students. 03:44.950 --> 03:50.590 Now we're going to use follow up and emersion calculate some function in order to calculate the total 03:50.590 --> 03:57.280 score for each student and after that at the results at the new property for our objects on the fly. 03:58.940 --> 04:01.610 OK, let's do it first, create for Loop. 04:03.350 --> 04:05.750 Variable, i.e., close to zero. 04:06.840 --> 04:07.260 Then. 04:08.690 --> 04:13.100 As a condition, right, I is less than students that length. 04:15.910 --> 04:17.650 And then I plus plus. 04:20.550 --> 04:26.730 As we said, we are going to act as the new properties, some of score one and score two, so. 04:26.730 --> 04:30.840 Right students, I got some. 04:33.220 --> 04:39.690 You remember that we were using dot notation in order to access and also to add the properties to objects, 04:40.420 --> 04:43.890 you also see that calculate some function, returns the value some. 04:44.440 --> 04:51.550 And in order to assign it to new property, we need to call this function here and pass at the arguments, 04:51.880 --> 04:54.480 score one and score two for each student. 04:55.150 --> 04:56.860 So right to calculate some. 04:58.530 --> 05:05.130 And as an argument, right, students, I thought score one. 05:07.530 --> 05:09.150 And then students I. 05:10.320 --> 05:11.730 That's got to. 05:13.500 --> 05:20.130 So, again, calculator function gives us as a value the sum of score one and score two, and we assign 05:20.130 --> 05:23.460 it as a value to the newly created property. 05:23.460 --> 05:27.270 Some, let's say, Castle, what this code exactly does. 05:27.900 --> 05:28.630 Right, Castle? 05:28.640 --> 05:29.970 That students. 05:31.800 --> 05:38.850 Reload and you can see Arae with our objects, if you take a look, you will see that objects have a 05:38.850 --> 05:42.430 new property, some with total scores for students. 05:42.930 --> 05:46.230 And again, note that this property was created on the fly. 05:47.540 --> 05:54.470 All right, now we need to check if a student has passed an exam or not, we know that overlimit is 05:54.470 --> 05:55.730 51 points. 05:56.270 --> 06:01.220 So we need to check if some, of course, is greater than or equal to 51. 06:02.280 --> 06:09.420 So creative statement with the condition students, I thought some. 06:11.270 --> 06:14.120 Is greater than or equal to 51. 06:16.490 --> 06:23.510 If this condition is true, if a student has passed an exam, then log their result in council and write 06:24.290 --> 06:25.250 Castlewood log. 06:26.710 --> 06:28.630 Students I. 06:30.300 --> 06:32.310 And use your name property. 06:33.360 --> 06:36.060 Plus, past final exam. 06:37.660 --> 06:38.470 Successfully. 06:41.590 --> 06:48.610 Revolt and you see that we got results for three students, John, Nick and Alex, and he tells us that 06:48.610 --> 06:50.860 they have passed final exams successfully. 06:51.980 --> 06:53.100 All right, fine. 06:53.720 --> 06:59.120 The next step is to figure out what was the final score for each student and according to that score, 06:59.130 --> 07:04.400 what kind of degree of diploma this student has got for that, I'm going to use again, follow. 07:04.670 --> 07:11.330 But before I do that, I want to demonstrate, just for your information, how Facebook works inside 07:11.330 --> 07:13.900 another club that's right below. 07:13.940 --> 07:15.110 A simple example. 07:15.380 --> 07:18.160 But before that, let's make a little broader here. 07:20.040 --> 07:22.770 So create follow up, right? 07:23.190 --> 07:24.120 Very well, I. 07:25.470 --> 07:27.450 And assigned to its Disvalue 100. 07:28.790 --> 07:32.000 Then as a condition, right eye is less than. 07:33.250 --> 07:34.350 Hundred and five. 07:35.900 --> 07:37.130 And then I plus plus. 07:39.760 --> 07:42.040 Inside the loop, create another one. 07:43.490 --> 07:44.000 And. 07:45.050 --> 07:53.330 Let's use here as a counter variable, X assigned to role, then right to condition X is less than 10. 07:55.250 --> 07:56.600 And then X plus plus. 07:59.270 --> 08:01.850 Let's log in council, the variable X. 08:04.630 --> 08:05.200 And then. 08:07.360 --> 08:10.030 Right outside Castle Deathlok. 08:11.590 --> 08:14.770 I reload the page. 08:15.930 --> 08:23.580 So you see, we have numbers from zero to nine and then 100, then again, numbers from zero to nine, 08:24.150 --> 08:29.460 then hundred and one, and it continues like this until the condition becomes false. 08:30.510 --> 08:31.640 Let's see what has happened. 08:32.280 --> 08:37.130 Generally, people are sometimes confused with that case because they think that, well, first of all, 08:37.130 --> 08:43.980 look, does its first iteration I mean, when I is 100, then the second follow up does one iteration 08:43.980 --> 08:44.250 two. 08:44.880 --> 08:45.940 But it's not true. 08:46.830 --> 08:53.340 So when first loop does its first iteration, then for loop inside it does all its iterations. 08:54.000 --> 08:56.180 You can obviously see it in this example. 08:56.700 --> 09:03.630 So here during the first iteration, when I is 100, the following site does all the situations and 09:03.630 --> 09:05.520 gives us the numbers from zero to nine. 09:06.210 --> 09:10.560 And after that we have hundreds from the first iteration, which belongs to the first follow. 09:11.810 --> 09:12.490 Makes sense. 09:14.010 --> 09:22.890 OK, so we're going to use this case in our task, let's comment it out and go back to our task, create 09:22.900 --> 09:25.140 another follow up and use. 09:26.510 --> 09:29.600 Another counteracts assigned to it. 09:29.630 --> 09:30.150 Zero. 09:30.860 --> 09:33.670 We need this loop to iterate through a race course. 09:33.680 --> 09:36.950 So I'm going to use length property, of course, right. 09:36.950 --> 09:40.310 As a condition, X is less than Schaus thought length. 09:41.800 --> 09:43.270 And that X plus plus. 09:45.610 --> 09:51.310 Then we need to create another statement inside Fallujah using this statement, I'm going to compare 09:51.310 --> 09:56.900 total scores of the students to scores which actually define a degree of the diploma. 09:57.430 --> 09:57.820 So. 09:57.820 --> 10:00.730 Right, if they're students, I. 10:01.970 --> 10:02.780 Not some. 10:04.680 --> 10:08.100 Is greater than or equal to Schaus X. 10:10.810 --> 10:16.570 So if this condition is true, if total score of the student is greater than or equal to the items inside 10:16.570 --> 10:21.880 a racecourse, then we need to get the result with the score and the degree which we need to get from 10:21.880 --> 10:22.830 the eight degrees. 10:23.740 --> 10:30.130 You see that both arrays have the same length and therefore, if total score is greater than one of 10:30.130 --> 10:34.390 the items from scores, then we need to get its appropriate degree. 10:35.380 --> 10:41.980 So, for example, if students score is greater than 91, then it's really what degree of diploma will 10:41.980 --> 10:42.400 be a. 10:43.810 --> 10:47.920 Makes sense, so we need to write the following cost a lot like. 10:49.620 --> 10:50.010 Then. 10:51.020 --> 10:51.770 He has. 10:53.240 --> 10:56.930 And plus students, I told some. 10:58.670 --> 11:02.900 Then again, plus some texture points and he got diploma. 11:05.980 --> 11:07.030 With a degree. 11:08.550 --> 11:10.920 And then plus, degrease ex. 11:13.400 --> 11:19.730 Again, we use degrees with index number X because scores and degrees iRace have the same length. 11:20.990 --> 11:26.090 Reload and you see that we got results that you may were not expecting. 11:26.360 --> 11:27.260 Let's explain it. 11:27.260 --> 11:34.370 In case of John, we know that John has 93 points, which is greater than all the items in a race course. 11:34.770 --> 11:37.550 Therefore, the condition is true for all the iterations of. 11:38.270 --> 11:40.860 And that's why we got five results instead of one. 11:41.480 --> 11:46.880 So when the condition becomes true, then we need immediately to stop loop iterations. 11:47.130 --> 11:49.430 And for that we need brake statements. 11:51.630 --> 11:55.140 Let's reload, and he said that the problem is fixed. 11:56.610 --> 12:01.020 OK, let's make your little border for better readability. 12:05.190 --> 12:05.790 Reloj. 12:07.570 --> 12:09.430 Now it's much nicer. 12:10.510 --> 12:11.080 All right. 12:11.110 --> 12:16.420 Almost everything is done, but you see that Bob is missing because he's failed and we need to show 12:16.420 --> 12:22.930 it for that creative statement, which will be a part of first if statement where we have checked if 12:22.930 --> 12:24.820 students have passed an exam or not. 12:26.410 --> 12:28.300 And run in council. 12:29.410 --> 12:30.250 Students. 12:31.920 --> 12:35.610 I don't name plus got. 12:37.490 --> 12:44.120 Then plus in place here with some of scores, students, I taught some. 12:45.830 --> 12:48.260 And then plus points. 12:49.770 --> 12:54.170 Has failed and has to try next year. 13:00.040 --> 13:02.290 And then make again little border. 13:04.760 --> 13:06.380 Reload the page and. 13:07.540 --> 13:09.160 Here we have Bob to. 13:10.550 --> 13:13.670 Now we can say that finally our task is done. 13:15.270 --> 13:20.760 OK, I think that everything was clear for you, you can test again the code we have written on your 13:20.760 --> 13:21.060 own. 13:21.510 --> 13:25.260 Also, you can feel free to add something to improve this task. 13:26.210 --> 13:31.480 I hope that you have enjoyed it and now little quiz is waiting for you, so let's move on.
