1
00:00:02,120 --> 00:00:05,210
In this course, up to this point,

2
00:00:05,210 --> 00:00:10,210
we now spent many hours diving into HTML and CSS

3
00:00:10,220 --> 00:00:14,520
because these are two extremely important languages

4
00:00:14,520 --> 00:00:19,040
which you need to build websites, to display content,

5
00:00:19,040 --> 00:00:22,150
to structure content and to style it.

6
00:00:22,150 --> 00:00:26,550
And we saw many demo examples, many projects,

7
00:00:26,550 --> 00:00:29,900
and you learned a lot about these languages.

8
00:00:29,900 --> 00:00:33,090
We also had a look at JavaScript

9
00:00:33,090 --> 00:00:37,240
which we can use to bring our website to life

10
00:00:37,240 --> 00:00:39,800
and add some interactivity.

11
00:00:39,800 --> 00:00:43,150
But all the things we learned up to this point

12
00:00:43,150 --> 00:00:46,600
happen and work in the browser only.

13
00:00:46,600 --> 00:00:49,620
We only had a look at the so-called frontend

14
00:00:49,620 --> 00:00:51,590
and in this course section,

15
00:00:51,590 --> 00:00:54,600
we now wanna take a step beyond the frontend.

16
00:00:54,600 --> 00:00:57,460
We wanna move onwards to the backend

17
00:00:57,460 --> 00:01:00,330
and therefore in this course section,

18
00:01:00,330 --> 00:01:04,580
you are going to learn what exactly such a backend is

19
00:01:04,580 --> 00:01:08,030
and why we need it for some websites.

20
00:01:08,030 --> 00:01:13,030
And for that, we are going to revisit how the web works

21
00:01:13,130 --> 00:01:17,550
so that we can understand where this backend fits in

22
00:01:17,550 --> 00:01:18,890
and why you need it.

23
00:01:18,890 --> 00:01:23,330
And we're then going to dive into more programming languages

24
00:01:23,330 --> 00:01:27,350
that you could learn for working on that backend

25
00:01:27,350 --> 00:01:29,963
for adding such backend code.
