DAVID J. MALAN: Hello, world.

4
00:00:19,580 --> 00:00:23,980
This is CS50 and this is web
programming with Python and JavaScript

5
00:00:23,980 --> 00:00:26,080
with CS50's own, Brian Yu.

6
00:00:26,080 --> 00:00:28,930
This course picks up where
CS50 itself leaves off,

7
00:00:28,930 --> 00:00:32,380
diving more deeply into the design
and implementation of web apps

8
00:00:32,380 --> 00:00:35,440
with Python, JavaScript
and SQL using frameworks

9
00:00:35,440 --> 00:00:38,035
like Django, React, and Bootstrap.

10
00:00:38,035 --> 00:00:41,980
BRIAN YU: We'll start by taking a
closer look out HTML and CSS, languages

11
00:00:41,980 --> 00:00:45,310
that we can use to describe the
structure and the style of web pages.

12
00:00:45,310 --> 00:00:47,620
After that, we'll introduce
Git, version control

13
00:00:47,620 --> 00:00:50,770
tool that we can use to keep track
of changes we make to our code,

14
00:00:50,770 --> 00:00:52,960
and also to allow multiple
people to collaborate

15
00:00:52,960 --> 00:00:55,240
on the same project at the same time.

16
00:00:55,240 --> 00:00:57,212
After that, we'll dive
more deeply into Python

17
00:00:57,212 --> 00:00:59,920
exploring some more advanced
features of the programming language

18
00:00:59,920 --> 00:01:01,840
and, in particular, how
we can use it in order

19
00:01:01,840 --> 00:01:05,650
to create dynamic web applications
using a web framework known as Django.

20
00:01:05,650 --> 00:01:07,630
We'll leverage Django,
and, in particular,

21
00:01:07,630 --> 00:01:11,260
its ability to deal with data, working
with SQL, models, and migrations

22
00:01:11,260 --> 00:01:13,900
to create web applications
that use a database in order

23
00:01:13,900 --> 00:01:16,600
to create interactive user experiences.

24
00:01:16,600 --> 00:01:19,600
After that, we'll dive more deeply
into another programming language--

25
00:01:19,600 --> 00:01:22,420
JavaScript-- exploring
how we can use JavaScript

26
00:01:22,420 --> 00:01:26,170
to create dynamic and interactive user
interfaces, writing code that responds

27
00:01:26,170 --> 00:01:29,110
to events, and also manipulates
a web page in response

28
00:01:29,110 --> 00:01:31,150
to some kind of user interaction.

29
00:01:31,150 --> 00:01:34,190
After that, we'll explore some
best practices in industry,

30
00:01:34,190 --> 00:01:37,750
including testing to make sure that
our code works as expected, and also

31
00:01:37,750 --> 00:01:40,150
continuous integration
and continuous delivery

32
00:01:40,150 --> 00:01:43,630
to allow us to rapidly make changes
and deploy those changes to our code

33
00:01:43,630 --> 00:01:45,850
whenever we're able
to make those updates.

34
00:01:45,850 --> 00:01:47,620
And then, finally,
we'll consider concerns

35
00:01:47,620 --> 00:01:50,770
around scalability and security
as we take our applications

36
00:01:50,770 --> 00:01:54,250
and move them from our own computers to
the web where anyone can access them.

37
00:01:54,250 --> 00:01:57,400
We'll talk about how we make sure that
these applications are able to scale

38
00:01:57,400 --> 00:02:00,330
and how we're able to make sure
that these applications are secure.

39
00:02:00,330 --> 00:02:02,830
Along the way, you'll have an
opportunity to put all of this

40
00:02:02,830 --> 00:02:05,800
into practice by building web
applications of your very own.

41
00:02:05,800 --> 00:02:07,290
BRIAN YU: This is CS50.
