Hello everyone.

2
00:00:01,490 --> 00:00:13,800
Welcome to this vigil on what is javascript java script is is scripting programming language that allows

3
00:00:13,800 --> 00:00:25,620
you to write programs that runs inside the web browser and ads interactivity and behaviour to a website.

4
00:00:25,950 --> 00:00:32,140
You may have heard of the programming language called Java.

5
00:00:32,280 --> 00:00:37,630
Java is not related to javascript.

6
00:00:37,920 --> 00:00:49,740
Java was very popular when javascript was first introduced in 1995 and for marketing reasons was named

7
00:00:50,010 --> 00:00:53,440
to take advantage of Java's popularity.

8
00:00:53,760 --> 00:01:05,610
Hence the name javascript which it has since been stuck with the room name for javascript is much script

9
00:01:06,140 --> 00:01:16,020
which was named after the MA organization that is responsible for the language standard.

10
00:01:16,110 --> 00:01:26,790
There has been several versions of my script the most recent version is Version 6 which is not yet adopted

11
00:01:26,820 --> 00:01:30,450
by or major Web browsers.

12
00:01:30,570 --> 00:01:40,020
Version 3 is what is currently adopted by all major Web browsers.

13
00:01:40,130 --> 00:01:47,340
Thus standard web technologies has three main layers.

14
00:01:47,340 --> 00:01:50,820
The first layer is see hastier melt.

15
00:01:50,820 --> 00:01:59,370
This is the mark-up language that we use to structure and give meaning to our Web content.

16
00:01:59,670 --> 00:02:11,740
For example would define in paragraphs headings and data to embed in images videos and all dues to it

17
00:02:11,760 --> 00:02:12,860
paints.

18
00:02:12,960 --> 00:02:26,300
The second layout is the csx which is the style rules that we chose to apply styling to our male content.

19
00:02:26,430 --> 00:02:36,060
For example this setting of the background colour or the positioning of the various images the way the

20
00:02:36,060 --> 00:02:41,330
pages lay out the type of fonts he chose for the content.

21
00:02:41,370 --> 00:02:45,030
All that is done using skill sets.

22
00:02:45,060 --> 00:02:56,610
The third layer is javascript which is a script in programming language that enables you to control

23
00:02:57,030 --> 00:03:05,610
things like multimedia animated images and any interaction on the web page.

24
00:03:05,700 --> 00:03:10,630
This is Facebook a very popular website.

25
00:03:10,650 --> 00:03:21,930
What you can see is the combined output of three distinct layers of code hastier Mail says javascript

26
00:03:22,260 --> 00:03:32,310
put together by the browser when you visit a website but browse up down the hastier email first and

27
00:03:32,660 --> 00:03:43,650
dexy's its content den downloads and that applies any services to the hastier mail funnel by download

28
00:03:43,770 --> 00:03:52,800
and running of javascript javascript is kept running inside the web browser in the background just to

29
00:03:52,800 --> 00:03:56,580
wait for any interaction to occur.

30
00:03:56,970 --> 00:04:05,710
An example of interaction can be entering your e-mail or password.

31
00:04:06,510 --> 00:04:13,780
In this video I covered what is Javascript in the next video.

32
00:04:13,860 --> 00:04:18,900
I will be talking about javascript syntax.

33
00:04:19,440 --> 00:04:24,090
Thank you for taking the time to watch this video.
