00:00:09,263 --> 00:00:13,690
Hi, everyone, I'm Guil, a JavaScript
developer and teacher here at treehouse.

3
00:00:13,690 --> 00:00:15,500
JavaScript is everywhere, and

4
00:00:15,500 --> 00:00:19,890
being used in all phases of development,
from software to hardware.

5
00:00:19,890 --> 00:00:23,180
Because of its power and
ability to run just about anywhere,

6
00:00:23,180 --> 00:00:26,790
JavaScript has become one of the most
necessary skills for a modern developer.

7
00:00:27,870 --> 00:00:31,380
By now, you might have some familiarity
with the JavaScript language.

8
00:00:31,380 --> 00:00:34,990
So in this course, we're going to briefly
step away from the text editor, and

9
00:00:34,990 --> 00:00:38,890
explore the modern landscape of
JavaScript, and what it means to learn and

10
00:00:38,890 --> 00:00:41,450
program with JavaScript today and beyond.

11
00:00:42,500 --> 00:00:45,970
Understanding JavaScript's history can
help make sense of its current state.

12
00:00:45,970 --> 00:00:49,810
So first, let's review some of
JavaScript's interesting past.

13
00:00:49,810 --> 00:00:51,990
JavaScript got its start in the browser.

14
00:00:51,990 --> 00:00:56,880
It all began in May of 1995, back then,
the internet was becoming popular,

15
00:00:56,880 --> 00:00:59,870
the web had become popular,
but the web was static.

16
00:00:59,870 --> 00:01:03,520
It wasn't always a place where you could
view videos of water skiing puppies, and

17
00:01:03,520 --> 00:01:05,690
photo galleries of juggling cats.

18
00:01:05,690 --> 00:01:09,160
You couldn't program web pages, so
they were often text heavy with at

19
00:01:09,160 --> 00:01:12,950
best images that floated to the right or
left side of the text.

20
00:01:12,950 --> 00:01:17,312
Not all that exciting really, but what
was exciting, is that a company called,

21
00:01:17,312 --> 00:01:21,226
Netscape communications,
had made the first commercial web browser,

22
00:01:21,226 --> 00:01:23,685
Netscape Navigator [SOUND],
and it was a hit.

23
00:01:23,685 --> 00:01:27,267
Soon after its release, Marc Andreessen,
the founder of Netscape,

24
00:01:27,267 --> 00:01:31,330
thought that the web needed a way to
become livelier and more dynamic.

25
00:01:31,330 --> 00:01:36,370
He believed that HTML needed a scripting
language, or a programming language, that

26
00:01:36,370 --> 00:01:41,130
could run natively in the browser, and add
small bits of functionality to a website.

27
00:01:41,130 --> 00:01:45,780
Like, respond to user interaction and
user input in real time, but also that was

28
00:01:45,780 --> 00:01:49,790
easy to use by non-professional
web designers and programmers.

29
00:01:49,790 --> 00:01:52,510
So they gave that job to Brendan Eich,
an engineer,

30
00:01:52,510 --> 00:01:57,000
who at the time was recruited by Netscape,
to embed a different type of programming

31
00:01:57,000 --> 00:02:00,070
language, called Scheme,
into Netscape navigator.

32
00:02:00,070 --> 00:02:02,480
But before he could get
started on that project,

33
00:02:02,480 --> 00:02:05,250
Eich got pulled into work on
the new scripting language.

34
00:02:05,250 --> 00:02:09,170
And in just ten days, he designed and
created a new programming language named,

35
00:02:09,170 --> 00:02:11,870
Mocha, the early name for JavaScript.

36
00:02:11,870 --> 00:02:16,050
Although it first developed under the name
Mocha, the languages' name was changed

37
00:02:16,050 --> 00:02:20,690
to LiveScript, when it first shipped in
beta releases of Netscape Navigator 2.0.

38
00:02:20,690 --> 00:02:24,800
And shortly after, as a marketing ploy
by Netscape to cash in on the success of

39
00:02:24,800 --> 00:02:29,850
then popular up and coming language, Java,
it was officially renamed to JavaScript.

40
00:02:29,850 --> 00:02:32,910
That's right!
Java and JavaScript are unrelated.

41
00:02:32,910 --> 00:02:36,480
They have nothing in common,
apart from being programming languages.

42
00:02:36,480 --> 00:02:40,620
Netscape just wanted a promotional edge
by connecting a brand new language,

43
00:02:40,620 --> 00:02:43,700
JavaScript, to a popular
language at the time, Java.

44
00:02:43,700 --> 00:02:49,550
So really, Java is to JavaScript, as ham
is to hamster, or as car is to carpet.

45
00:02:49,550 --> 00:02:50,570
You get the idea.

46
00:02:50,570 --> 00:02:53,840
So don't make the mistake of confusing
the two, especially at a job interview.

47
00:02:55,340 --> 00:02:59,660
Netscape's vision of a livelier web
consisting of interacting pages came true.

48
00:02:59,660 --> 00:03:02,000
In many ways far greater than expected.

49
00:03:02,000 --> 00:03:04,810
JavaScript is now the programming
language of the web.

50
00:03:04,810 --> 00:03:07,240
It runs in all major browsers.

51
00:03:07,240 --> 00:03:10,434
Now, there's more to the story, and
we'll get back to it just a bit.

52
00:03:10,434 --> 00:03:11,850
So coming up in this course,

53
00:03:11,850 --> 00:03:15,982
you're going to learn about the evolution
of JavaScript, through the years, and

54
00:03:15,982 --> 00:03:20,000
the different types or flavors of
JavaScript available to developers.

55
00:03:20,000 --> 00:03:23,593
We'll discuss common tools, JavaScript
developers use in the workflows,

56
00:03:23,593 --> 00:03:26,980
how they use those tools in
their day to day work, and more.

57
00:03:26,980 --> 00:03:30,550
The landscape of JavaScript is
constantly changing and evolving, so

58
00:03:30,550 --> 00:03:34,120
make sure that you check the teacher's
notes with each video, because there will

59
00:03:34,120 --> 00:03:37,470
be additional resources, and up to date
information about most of what I'll cover.
