Drupal 9/8 Views - How to Group Contents categorized by Taxonomy Terms: Series 1

This demo and tutorial quickly show how to group contents in a listing page that are categorized or classified according to Vocabulary Terms (Taxonomy). This video would assume you are already familiar with creating your own content type, creating vocabulary terms in taxonomy, and some basic usage of the module Views in Drupal 7, 8 and 9.
For example, you need to have a listing that displays content as below:
Group 1
[table here of contents categorized under Term 1]
Group 2
[table here of contents categorized under Term 2]
This video series on Groupings using Views will be followed by another quick video on how to sort these groupings in any custom manner as preferred. Series 2 video will follow shortly.

How do you group it without the table format? Like a list format instead.

You can still do that, same steps, but you would probably work some more with CSS to get desired layout/format.
