1
00:00:00,660 --> 00:00:08,200
Array elements can be changed using the index number let's change the first element of our array to

2
00:00:08,200 --> 00:00:08,800
Kiwi

3
00:00:16,790 --> 00:00:24,680
we'll start off with the name of the array fruits and then specify the index number corresponding to

4
00:00:24,680 --> 00:00:26,270
the value we want to amend

5
00:00:35,830 --> 00:00:36,450
and that's it.

6
00:00:36,460 --> 00:00:39,520
Once we save our file we can preview it in our web browser

7
00:00:46,500 --> 00:00:52,690
and we can now see that the first value Apple has been amended to Kiwi

8
00:00:56,550 --> 00:01:01,490
if we were to change the index number let's say the three

9
00:01:04,160 --> 00:01:05,950
and save our file and refresh

10
00:01:09,590 --> 00:01:12,290
we can see that grape has now changed to Kiwi

11
00:01:18,920 --> 00:01:23,210
we can also delete elements in an array using index numbers as well.

12
00:01:24,100 --> 00:01:30,260
Let's delete pear from our list of elements since pear would have the index number two.

13
00:01:30,370 --> 00:01:31,810
We can type the following

14
00:01:44,440 --> 00:01:45,370
we'll save our file

15
00:01:51,070 --> 00:01:56,810
and in our web browser we can now see that there is an empty space where pear would have appeared.
