00:00:02,460 --> 00:00:06,090
Earlier in this course, we had a look at Javascript libraries,

2
00:00:06,090 --> 00:00:11,150
we had a look at axios, Lodash, JQuery as some examples.

3
00:00:11,160 --> 00:00:18,330
Now in this module, we'll explore Javascript frameworks, these in the end are like bigger libraries you could

4
00:00:18,330 --> 00:00:24,810
say but we'll have a look at what exactly a framework is, how it helps you focus on what matters and

5
00:00:24,810 --> 00:00:29,240
how it simplifies the project building or app building work

6
00:00:29,400 --> 00:00:31,510
and we'll also see an example.

7
00:00:31,590 --> 00:00:38,520
Now to be precise, I'll first of all dive into what exactly a framework is and what the difference to

8
00:00:38,520 --> 00:00:46,830
a library is and we'll then have a look at React.js which ironically is a library but a pretty important

9
00:00:46,830 --> 00:00:47,570
and huge one

10
00:00:47,700 --> 00:00:53,350
and if we then add a couple of other things from the React ecosystem, it actually gets more framework-ish.

11
00:00:53,370 --> 00:00:57,480
So we'll have a look at that and see why that matters,

12
00:00:57,480 --> 00:01:04,260
what's great about React, what alternatives to React are and how that can help us in our projects.
