1
00:00:02,220 --> 00:00:08,100
So you learned a lot about the Javascript syntax and how to write Javascript code and obviously that's

2
00:00:08,100 --> 00:00:09,530
what this course is about.

3
00:00:09,570 --> 00:00:14,150
Now in this module, we'll also dive in an important related topic

4
00:00:14,160 --> 00:00:20,790
and that would be performance optimizations because of course it's nice that we're able to write Javascript

5
00:00:20,790 --> 00:00:27,180
code but we want to write good Javascript code and most importantly, you should be able to find out whether

6
00:00:27,180 --> 00:00:34,710
you wrote code that offers a good performance to your end users or whether there are things you can

7
00:00:34,710 --> 00:00:39,480
improve or you might need to fix to avoid a bad user experience.

8
00:00:39,480 --> 00:00:46,530
Specifically in this module, we'll have a look at what exactly performance is because it turns out that

9
00:00:46,530 --> 00:00:50,240
is rather a broad term and it can be a lot of different things.

10
00:00:50,280 --> 00:00:57,270
We'll also have a look at some tools or approaches of measuring and analyzing performance and finding

11
00:00:57,270 --> 00:01:00,540
out how our application behaves.

12
00:01:00,660 --> 00:01:07,950
We'll also dive into some potential optimization ideas on how you could improve your code and what you

13
00:01:07,950 --> 00:01:09,480
should watch out for

14
00:01:09,660 --> 00:01:16,950
and I will also guide you to some additional resources because the whole topic of optimizing performance

15
00:01:17,310 --> 00:01:19,950
does not stop at Javascript,

16
00:01:19,950 --> 00:01:24,300
wWhat this course of course is about but actually includes a broad variety of things

17
00:01:24,360 --> 00:01:28,930
and even for Javascript, it turns out there are a lot of different use cases.

18
00:01:28,950 --> 00:01:32,250
So in this module, I want to get you started,

19
00:01:32,250 --> 00:01:38,100
we'll dive deeply into all the important concepts but thereafter I'll also give you the tools so that

20
00:01:38,100 --> 00:01:46,220
you can build up on this and analyze and optimize any part of your web site, of your web application.

21
00:01:46,230 --> 00:01:47,280
So let's dive right in.
