WEBVTT

00:00:06.600 --> 00:00:16.510
More so now so you get to learn how to add an array inside an array.

00:00:16.910 --> 00:00:17.510
OK.

00:00:17.760 --> 00:00:23.860
So you're going to use a function we call a race place.

00:00:23.910 --> 00:00:30.360
This function is going to allow us to add any elements we want inside an array in a certain position

00:00:30.360 --> 00:00:30.380
.

00:00:30.390 --> 00:00:30.780
So

00:00:34.680 --> 00:00:39.450
the function is going to take a few promises so the first one is going to be the array in question it's

00:00:39.450 --> 00:00:40.500
going to be shopping baskets

00:00:43.320 --> 00:00:44.010
and

00:00:46.830 --> 00:00:52.320
then we're going to have a strong position.

00:00:54.990 --> 00:01:05.910
Let's go for zero for example and then we're going to specify how many items we want to delete from

00:01:05.910 --> 00:01:06.530
that position.

00:01:06.540 --> 00:01:10.340
So let's add that to two.

00:01:10.350 --> 00:01:11.850
OK.

00:01:12.890 --> 00:01:17.670
And finally let's have an array we want to insert.

00:01:17.760 --> 00:01:24.870
So we want to insets for example and an array with a couple of elements Mongo and Kuei

00:01:27.490 --> 00:01:39.940
paint and then we're going to print the shopping Muskie's again and see what the result is.

00:01:42.810 --> 00:01:44.250
OK so if you're approached a page

00:01:47.850 --> 00:01:54.850
with an error then we need to make penances.

00:01:54.900 --> 00:01:57.620
So if you press the page OK.

00:01:58.230 --> 00:01:58.740
So now

00:02:02.610 --> 00:02:12.670
our array is OK first of all just add a paragraph just before printing the array.

00:02:13.030 --> 00:02:16.870
That's it's more visible.

00:02:17.670 --> 00:02:22.890
Does it go shopping baskets.

00:02:25.410 --> 00:02:26.030
OK great.

00:02:26.100 --> 00:02:27.430
Let's refresh now.

00:02:27.840 --> 00:02:28.350
OK.

00:02:28.590 --> 00:02:33.630
So now our shopping basket as we see so what's happened is

00:02:39.000 --> 00:02:43.610
before that's ok we started from this.

00:02:43.620 --> 00:02:49.540
OK so this is the original value before we use the array splice function.

00:02:49.800 --> 00:02:53.400
OK let's add another paragraph just before this as well.

00:02:53.710 --> 00:02:55.410
It's more readable.

00:02:56.030 --> 00:02:58.780
OK.

00:03:00.890 --> 00:03:02.010
OK let's.

00:03:02.390 --> 00:03:06.120
OK so before using the array splice function.

00:03:06.120 --> 00:03:10.800
So this is the original shopping basket.

00:03:10.920 --> 00:03:15.720
So we started our position 0.

00:03:16.410 --> 00:03:22.840
OK so we started there and we deleted a couple of items.

00:03:23.000 --> 00:03:27.540
So we chose two to delete so we deleted this one.

00:03:28.410 --> 00:03:29.310
OK.

00:03:29.340 --> 00:03:34.530
And this one.

00:03:37.450 --> 00:03:40.850
OK so first want bread and milk.

00:03:41.670 --> 00:03:46.710
So we deleted both of them and then we inserted this new array.

00:03:47.130 --> 00:03:49.170
OK.

00:03:49.940 --> 00:03:50.940
And we can see that.

00:03:50.940 --> 00:03:53.150
So Mongo cute.

00:03:54.830 --> 00:04:00.570
And then we continue with the other values of the original array.

00:04:01.590 --> 00:04:02.040
OK.

00:04:02.040 --> 00:04:02.760
So that's how it works.

00:04:02.760 --> 00:04:05.760
So the array splice function.

00:04:05.760 --> 00:04:10.100
So it will take an array as the first barometer.

00:04:10.110 --> 00:04:19.970
So if we specify the start position that is going to start from the deletes whatever we say literally

00:04:20.030 --> 00:04:20.100
.

00:04:20.160 --> 00:04:23.870
So if we said this to 0 for example.

00:04:23.930 --> 00:04:25.680
So we're not releasing anything.

00:04:26.070 --> 00:04:28.140
Then the results are going to be different.

00:04:28.140 --> 00:04:34.310
So if you're a page now we can see that we want to position zero.

00:04:34.700 --> 00:04:40.830
And just before position is 0 we are that Mangu and Kuei and we haven't deleted anything.

00:04:41.280 --> 00:04:51.690
OK but if we said that to 4 for example then that means that's opposite positions 0 we go into the leads

00:04:51.780 --> 00:04:57.550
for items and then just before we going to insert the new array.

00:04:57.660 --> 00:04:58.080
OK.

00:04:58.080 --> 00:05:04.440
So if the refresh the page this time we can see that we have deleted four items.

00:05:04.440 --> 00:05:07.060
Bread milk eggs and bread.

00:05:07.260 --> 00:05:08.060
OK.

00:05:08.070 --> 00:05:09.930
And then right before

00:05:13.110 --> 00:05:17.750
we have said that when you read that Mongo.

00:05:18.250 --> 00:05:25.340
OK so that's how the erase splice function works ok.

00:05:27.680 --> 00:05:28.240
Or it's

00:05:30.110 --> 00:05:32.190
.

00:05:35.280 --> 00:05:37.810
Now let's see how to sort.

00:05:37.820 --> 00:05:44.500
A certain array in ascending order so the function is pretty straight straightforward.

00:05:44.520 --> 00:05:50.870
It's Salt's followed by the name of the array to sort.

00:05:51.090 --> 00:06:00.990
OK Saud's shopping baskets and what's going to happen is that the value of the array is going to change

00:06:01.080 --> 00:06:04.460
and it's going to be sorted in ascending order.

00:06:04.640 --> 00:06:05.270
OK.

00:06:05.580 --> 00:06:08.040
So let's just echo this again

00:06:11.690 --> 00:06:16.400
and say sorted in ascending order.

00:06:17.160 --> 00:06:21.810
So if we refresh the page we can see that's our array.

00:06:21.810 --> 00:06:24.400
Now is sorted in ascending order.

00:06:24.660 --> 00:06:25.000
OK

00:06:31.790 --> 00:06:35.430
so is saucing with Upal then banana biscuits.

00:06:35.460 --> 00:06:39.320
I can see how the alphabetical order is followed.

00:06:39.620 --> 00:06:41.610
OK.

00:06:42.540 --> 00:06:51.840
All right if you want to sauces in descending order rather than using Saud's we can just use

00:06:58.260 --> 00:07:00.300
our sort for Reavis.

00:07:00.360 --> 00:07:00.830
OK.

00:07:01.110 --> 00:07:02.960
So now if we refresh.

00:07:03.280 --> 00:07:04.080
It's going to be

00:07:09.180 --> 00:07:12.240
it's going to be done the opposite way.

00:07:12.240 --> 00:07:16.030
So we finish with Apple and we start with yogurts.

00:07:16.080 --> 00:07:17.270
All right.

00:07:18.300 --> 00:07:23.740
OK so let's go back to the ascending order.

00:07:26.020 --> 00:07:28.620
OK.

00:07:29.400 --> 00:07:31.170
Now let's see how to source.

00:07:31.230 --> 00:07:32.400
As to race.

00:07:32.400 --> 00:07:32.900
OK.

00:07:33.000 --> 00:07:35.280
So let's creates an obsessive array.

00:07:35.310 --> 00:07:37.880
Call it comics.

00:07:38.840 --> 00:07:39.790
OK and we're going to

00:07:43.500 --> 00:07:54.040
place three elements the same size with.

00:08:00.060 --> 00:08:02.520
OK.

00:08:04.920 --> 00:08:07.530
So let's start with B-M.

00:08:07.690 --> 00:08:21.030
W is the key and with us to make and then the model X5 and then let's have the key.

00:08:21.200 --> 00:08:35.700
The second one is the make the model a 6 and the last one the key Mercedes for the make and the model

00:08:35.820 --> 00:08:39.230
is go for Cialis.

00:08:39.240 --> 00:08:41.310
OK.

00:08:43.800 --> 00:08:44.040
OK.

00:08:44.040 --> 00:08:50.630
So let's print this array before we sort it.

00:08:50.670 --> 00:08:52.410
So let's echo a paragraph first

00:08:54.930 --> 00:08:55.610
saying

00:08:59.710 --> 00:09:01.890
comics.

00:09:02.730 --> 00:09:11.820
And after that list brings the array using the print function and erase card makes.

00:09:11.990 --> 00:09:14.580
OK.

00:09:16.410 --> 00:09:16.930
OK.

00:09:17.040 --> 00:09:19.500
So that's our array.

00:09:20.250 --> 00:09:24.880
Ex wife.

00:09:27.760 --> 00:09:28.290
OK.

00:09:28.440 --> 00:09:29.560
So that's our array.

00:09:29.700 --> 00:09:40.740
Now we going to see how to sort the array either using the we you're going to start in ascending order

00:09:40.980 --> 00:09:46.260
by value or by key or by keys.

00:09:46.500 --> 00:09:51.020
OK so it starts with sorting by value.

00:09:51.310 --> 00:10:00.720
OK so we're going to use the function a sort.

00:10:01.160 --> 00:10:09.230
OK so this function is going to source the array in an ascending order by value.

00:10:09.270 --> 00:10:10.380
All right.

00:10:11.060 --> 00:10:14.560
Let's try this.

00:10:14.880 --> 00:10:18.210
Now if we preens the array again

00:10:20.990 --> 00:10:28.870
and this time he's going to be sorted in ascending order by Valy.

00:10:29.650 --> 00:10:32.940
OK so let's try this.

00:10:32.940 --> 00:10:38.900
So now if you look at the Values code A-6 CNS and then X5.

00:10:38.910 --> 00:10:42.520
So we have sorted the array in ascending order by value.

00:10:42.600 --> 00:10:44.040
OK.

00:10:46.260 --> 00:10:52.410
If we use the function a all.

00:10:52.440 --> 00:10:59.910
Rather than a source for reverse then it's going to be sorted in the opposite order by value.

00:11:00.080 --> 00:11:02.940
You can see every saucing this time by X5.

00:11:02.940 --> 00:11:04.580
That's less than a six.

00:11:04.650 --> 00:11:07.570
OK let's go back to the ascending order.

00:11:07.730 --> 00:11:08.690
OK.

00:11:09.030 --> 00:11:17.210
And now we are going to source the array by keys rather than values.

00:11:17.250 --> 00:11:23.310
So this time we are going to use another function that is called K sort's ok.

00:11:23.710 --> 00:11:30.060
K for keys and it is with the name of the array.

00:11:30.360 --> 00:11:37.500
Unless preens the array after this by this time we're going to say complex sorted in ascending order

00:11:37.610 --> 00:11:40.390
Viki's.

00:11:42.210 --> 00:11:46.500
OK so now if we refresh the page you can see that's

00:11:49.760 --> 00:11:50.350
the keys.

00:11:50.370 --> 00:11:53.570
Starts with Audi then BMW then Mercedes.

00:11:53.620 --> 00:11:54.210
OK.

00:11:54.470 --> 00:12:05.520
And similarly to sorting by values we can also sort of buy keys in the descending order if we add our

00:12:06.000 --> 00:12:06.690
after.

00:12:06.900 --> 00:12:09.440
OK.

00:12:09.480 --> 00:12:14.880
And you can see that now we sousing with Mercedes finishing with Audi.

00:12:15.680 --> 00:12:18.520
OK let's go back to the previous one.

00:12:18.930 --> 00:12:19.690
OK.

00:12:20.100 --> 00:12:30.990
So there was a quick overview of some important functions we can use in BHP to manipulate arrays we

00:12:30.990 --> 00:12:38.490
might cover other functions later on when we are building Web sites like converting arrays to strings

00:12:38.490 --> 00:12:41.640
or strings to arrays.

00:12:41.850 --> 00:12:47.220
OK so in the next video we'll learn how to send an email using BHB
