World Background
The world background is one of the more neglected areas in beginning Blender tutorials. I think how it works should be understood early on.
The primary setting in the World Settings is the background setting. For me this is an extrmemly important setting. It can be used to change the background to a solid black, which is much easier on the eyes.
Beyond that, to make small images with different backgrounds, and this setting allows that.
I did a search on world background and got this:

Not anything on what the different methods are, or why you would use them.
Basically you have three options. You can use the Shader to create a background , you can us an HDRI background, or you can set the background to transparent.
The World setting in the Shader.
This is the default setting when you first open Blender. This is simply set up by changed the base color in your material tab. I almost always set it to solid black. Much more advanced colors can be created in the Shader Node Editor as you become more skilled in working with Blender.
