Installing jQuery
The question is where to find jQuery. Well, you can find it at http://jquery.com/. I have also attached the file with this book. You can download it from there.
If you go to http://jquery.com/, you will see the following screen:
Click the Download jQuery button. You will be redirected to the following page:
There are two versions of jQuery: 1.x.x and 2.x.x. There are just a few differences between these versions. The compressed version's code is not readable as the version does not have blank spaces and comments; however, the uncompressed version is clearly coded and formatted, it also has important comments to understand the code and functions' work. If you want to learn how a function of jQuery works, I would suggest you to go through the jQuery uncompressed version.
Throughout this chapter, we will use the 2.x.x version. The latest version of 2.x.x is 2.2.0.
Note
You can download the compressed or uncompressed version of jQuery.
I'll advice you to use the compressed...
