The longer the distance, the larger the diameter of the wire you need, due to resistance/heat.
Typically, extension cords are going to be manufactured with the thinnest wire they can get away with based on the safety requirements, in order to save on materials cost.
So plugging 2 short cords together might cover the same distance as 1 longer cord, but the longer cord will use thicker wire to maintain the proper margin of safety.
One thing you could do is start trying to understand those commands.
Read the man pages or the documentation to figure out what the commands are actually doing. Once you have the “what” , you can dig deeper to get to the “why” if it isn’t obvious by that point.
After enough of that, you’ll go to copy/paste and already understand what it’s doing without needing to look it up again.
Then from there, it’s a matter of building the instinct to be able to say “I need to do X, so I’ll use commands Y and Z.”
