Welcome to jQuery 101, jQuery for beginners.

2
00:00:03,645 --> 00:00:05,435
Let's start with the big question.

3
00:00:05,430 --> 00:00:07,350
Is jQuery still used?

4
00:00:07,350 --> 00:00:09,120
And the answer is absolutely yes.

5
00:00:09,120 --> 00:00:14,580
Jquery is responsible for the JavaScript on hundreds of millions of websites.

6
00:00:14,580 --> 00:00:16,230
I'm going to repeat that.

7
00:00:16,230 --> 00:00:22,590
Jquery is responsible for the JavaScript on hundreds of millions of websites.

8
00:00:22,589 --> 00:00:25,619
Jquery was originally created to bridge a gap between

9
00:00:25,620 --> 00:00:28,520
browsers before JavaScript started becoming more standardized,

10
00:00:28,515 --> 00:00:31,055
Internet Explorer and Firefox use JavaScript differently.

11
00:00:31,050 --> 00:00:33,780
Chrome and Safari implemented JavaScript differently.

12
00:00:33,775 --> 00:00:39,185
And jQuery was how you could rate one language that just worked.

13
00:00:39,185 --> 00:00:43,105
Look, I know lots of people say you should skip learning jQuery altogether,

14
00:00:43,100 --> 00:00:45,460
but consider this if it's used by over

15
00:00:45,455 --> 00:00:47,905
a 100 million websites and still favored by

16
00:00:47,900 --> 00:00:50,650
organizations like Django and the jangle framework,

17
00:00:50,645 --> 00:00:55,415
then there is clearly a market demand for this skill.

18
00:00:55,415 --> 00:00:57,725
If you're getting into JavaScript recently,

19
00:00:57,725 --> 00:00:59,155
this course is for you.

20
00:00:59,150 --> 00:01:01,310
If you're a back-end developer and you want to write

21
00:01:01,310 --> 00:01:05,000
nice JavaScript without needing to learn an entire framework like react,

22
00:01:05,000 --> 00:01:07,510
this course is for you.

23
00:01:07,505 --> 00:01:09,095
To get the most out of this course.

24
00:01:09,095 --> 00:01:11,725
You will need to know a little bit of HTML.

25
00:01:11,720 --> 00:01:13,560
And if you know a little CSS,

26
00:01:13,564 --> 00:01:16,254
that's going to be helpful, but it's not required.

27
00:01:16,250 --> 00:01:18,940
And to really make the most out of jQuery,

28
00:01:18,935 --> 00:01:23,375
you should know some plain old just vanilla JavaScript.

29
00:01:23,375 --> 00:01:28,045
Hi, I'm Caleb, tell me and I've been using jQuery since it was invented in 2006.

30
00:01:28,040 --> 00:01:32,030
I've taught over 300 thousand students and worked with clients such as nasa,

31
00:01:32,030 --> 00:01:33,890
Mozilla, the Arctic Research Foundation,

32
00:01:33,890 --> 00:01:37,010
Samaritans, and the National Health Service in the UK.

33
00:01:37,010 --> 00:01:40,270
And this is my jQuery 101 class.

34
00:01:40,265 --> 00:01:42,065
Thanks for watching this introduction video,

35
00:01:42,065 --> 00:01:44,315
and I'll see you inside.
