Hello and welcome him this feed you.

2
00:00:02,970 --> 00:00:12,450
I will introduce you to charvat Script German script is one of the three languages that a web developer

3
00:00:12,660 --> 00:00:24,780
must learn what is javascript jamas script is a programming language that adds interactivity to your

4
00:00:24,900 --> 00:00:26,210
website.

5
00:00:26,220 --> 00:00:36,780
The interactivity can be when a button is pressed or when data is entered into a form.

6
00:00:36,780 --> 00:00:39,190
It can even be animations.

7
00:00:39,420 --> 00:00:47,160
So when you go to a website any time you notice some interaction or where you have to press a button

8
00:00:47,750 --> 00:00:54,780
maybe complete a form does interactions are made possible by javascript.

9
00:00:54,780 --> 00:01:07,860
When javascript is applied to an hastier middle document it makes the document dynamic and it has interactivity

10
00:01:08,010 --> 00:01:10,950
to their website.

11
00:01:11,670 --> 00:01:16,790
Javascript was invented by Brendan.

12
00:01:16,800 --> 00:01:28,000
It is the co-founder of the mod large corporation which also is responsible for the Firefox web browser.

13
00:01:28,140 --> 00:01:31,500
Javascript is not Java.

14
00:01:31,530 --> 00:01:38,790
There is a completely separate language programming language called Java so they are different in design

15
00:01:39,300 --> 00:01:42,250
and other aspects as well.

16
00:01:42,300 --> 00:01:48,700
Javascript is one of the three languages or web developers must learn.

17
00:01:48,870 --> 00:01:58,770
The other two languages are hastier male and csx another key this pinchuk javascript is that javascript

18
00:01:58,950 --> 00:02:01,310
is case sensitive.

19
00:02:01,530 --> 00:02:10,260
So if you declare something with a lower case and let on try to access that with an up by case it will

20
00:02:10,260 --> 00:02:13,080
not work because they are two separate things.

21
00:02:13,080 --> 00:02:17,170
It creates cases separately upper case and lower.

22
00:02:17,300 --> 00:02:25,350
And is at two different things in Javascript so when you write in javascript code you need to be careful

23
00:02:25,480 --> 00:02:26,690
with your cases.

24
00:02:26,800 --> 00:02:32,340
Few years in lower case to define some things to lower case.

25
00:02:32,640 --> 00:02:36,230
That's it for this introduction to javascript.

26
00:02:36,270 --> 00:02:38,080
Thank you and bye for now.
