1
00:00:00,530 --> 00:00:01,790
Welcome to Unit three.

2
00:00:01,790 --> 00:00:04,260
If you've completed the courses and
projects for

3
00:00:04,260 --> 00:00:08,270
the last two units, you've done a fair
amount of work with JavaScript.

4
00:00:08,270 --> 00:00:13,200
You've learned about arrays, objects,
functions, DOM manipulation and more.

5
00:00:13,200 --> 00:00:14,600
Congratulations.

6
00:00:14,600 --> 00:00:18,360
You know more about JavaScript
than most people in the world.

7
00:00:18,360 --> 00:00:20,160
You've got a lot more to learn,
but believe it or

8
00:00:20,160 --> 00:00:23,655
not, you're actually
a developer right now.

9
00:00:23,655 --> 00:00:26,299
Websites, like Amazon, Ebay, Facebook, and

10
00:00:26,299 --> 00:00:30,780
Netflix rely on web forms to collect
information from their customers.

11
00:00:30,780 --> 00:00:34,490
In fact, creating forms is
a common task for a web developer.

12
00:00:34,490 --> 00:00:37,720
In this unit,
you'll learn all about html forms.

13
00:00:37,720 --> 00:00:39,810
You'll also learn how to
make forms interactive,

14
00:00:39,810 --> 00:00:41,670
and respond to the input from a user.

15
00:00:42,830 --> 00:00:45,570
You'll learn how to make sure
the input like the name here is valid.

16
00:00:46,730 --> 00:00:48,410
This makes sure we're getting good data.

17
00:00:49,910 --> 00:00:53,680
You'll also adjust the actual
form based on what the user does.

18
00:00:53,680 --> 00:00:55,120
Like selecting a job role.

19
00:00:55,120 --> 00:01:00,511
Or a t-shirt design.

20
00:01:02,450 --> 00:01:06,140
JavaScript lets you change
a form dynamically like this.

21
00:01:06,140 --> 00:01:11,100
Notice when I select an event,
any events that conflict with the time

22
00:01:11,100 --> 00:01:14,530
of my selected event are greyed out and
can't be selected.

23
00:01:14,530 --> 00:01:18,520
These are great examples of how
JavaScript can make forms smarter and

24
00:01:18,520 --> 00:01:20,310
more user friendly.

25
00:01:20,310 --> 00:01:22,120
This project is a great challenge for

26
00:01:22,120 --> 00:01:24,460
your growing JavaScript skills,
have fun with it.

27
00:01:25,710 --> 00:01:29,160
To get ready for the project, check out
the description and instructions for

28
00:01:29,160 --> 00:01:30,600
the project now.

29
00:01:30,600 --> 00:01:34,170
If you'd look at what you need to build
in this unit now, your mind will start

30
00:01:34,170 --> 00:01:37,930
thinking up solutions as you go
through the courses and workshops.

31
00:01:37,930 --> 00:01:39,630
Have fun and see you again soon.
