1
00:00:02,470 --> 00:00:08,830
As part of this course, we already worked with events, for example the click event which we listened to

2
00:00:08,830 --> 00:00:10,360
on buttons.

3
00:00:10,420 --> 00:00:16,630
Now there are more events we can listen to and events in general are an important thing in Javascript,

4
00:00:16,990 --> 00:00:22,870
not just when working with Javascript in the browser but in Javascript in general, though in this module,

5
00:00:22,870 --> 00:00:26,220
again I will focus on the browser side Javascript,

6
00:00:26,220 --> 00:00:28,820
you'll get an idea for how we listen to events

7
00:00:28,840 --> 00:00:35,050
in Node.js for example, in the Node.js module later down in the course and I will show you to which

8
00:00:35,050 --> 00:00:36,800
kind of events you can listen,

9
00:00:36,880 --> 00:00:42,400
which data you will get there and how to work with that data and also how to control the behavior of

10
00:00:42,400 --> 00:00:43,240
events.

11
00:00:43,270 --> 00:00:49,900
We'll also finish this module by going back to our projects project where we switched projects

12
00:00:49,900 --> 00:00:55,620
between these two lists which we worked on in an earlier module and we'll implement drag and drop there.

13
00:00:55,660 --> 00:01:01,720
So specifically in this module, we'll have a look at events, what they are, how they work, which data

14
00:01:01,720 --> 00:01:02,950
they yield to us,

15
00:01:03,130 --> 00:01:07,660
we'll then also as I mentioned have a look at how we can control their behavior, specifically how we

16
00:01:07,660 --> 00:01:14,580
can control what they do and how they propagate and what event propagation actually means

17
00:01:14,680 --> 00:01:20,740
and as I also mentioned, we'll implement an example with drag and drop which is a nice user interface

18
00:01:20,740 --> 00:01:23,580
pattern that you might need in many applications

19
00:01:23,710 --> 00:01:29,320
and it is all powered by events which are built into the browser or which are exposed by the browser.
