1
00:00:02,370 --> 00:00:04,290
So this is it with this module.

2
00:00:04,320 --> 00:00:11,070
We learned a lot about Node.js, that it uses regular Javascript syntax but adds its own APIs, like

3
00:00:11,070 --> 00:00:17,640
the filesystem, its own packages we can use and does of course not support the browser default APIs

4
00:00:17,640 --> 00:00:24,090
like the DOM or browser storage because it doesn't run in the browser but that instead we run Javascript

5
00:00:24,180 --> 00:00:30,620
in a different environment, on our machine or on any machine where Node.js is installed.

6
00:00:30,660 --> 00:00:36,250
We can also not just use Node.js to run utility scripts like this one, we can use it to set up a HTTP

7
00:00:36,300 --> 00:00:42,990
server, either by doing everything on our own or by tapping into the rich ecosystem that exists

8
00:00:42,990 --> 00:00:49,170
around Node.js, where we have packages and frameworks like Express and other packages together with

9
00:00:49,170 --> 00:00:54,720
Express.js, that allow us to focus on our core business logic and where we don't have to worry about

10
00:00:54,720 --> 00:00:56,180
parsing data and so on.

11
00:00:56,790 --> 00:01:02,820
And there you learned how you can set up a server which returns some server side rendered HTML files

12
00:01:03,330 --> 00:01:10,440
or how you can create a so-called REST API, where you have various endpoints, various URLs you

13
00:01:10,440 --> 00:01:18,270
support on that server that do different tasks depending on the HTTP method path combination that reaches

14
00:01:18,270 --> 00:01:19,380
your server.

15
00:01:19,380 --> 00:01:23,370
You even learned how to store data in a database and get it from there

16
00:01:23,460 --> 00:01:29,750
and with that you should have a good idea of which problem Node.js solves, how it generally works, that

17
00:01:29,750 --> 00:01:36,480
it's just Javascript in the end but with a totally different purpose or giving you totally different

18
00:01:36,570 --> 00:01:38,680
options of what you can do with it

19
00:01:38,910 --> 00:01:45,630
and therefore now you really have a broad overview of Javascript and what you can do with it and where

20
00:01:45,630 --> 00:01:48,750
you can run it and what that means for your applications.
