In Norwegian we use the terms "Christmas calendar" and "Advent calendar" (translated directly) interchangeably. This i probably why some of the calendars (under the https://bekk.christmas umbrella) are using the term incorrectly
It might be that way where you work, but that's definitely not the case here.
In fact, I think what you suggest would be an extremely short-sighted "strategy" for a consultancy. Sure, you might get the next contract working this way. But once the customer could get rid of you they would, and they would never hire you again.

The language is a simplified variant of Lisp. This is just a toy language, so a lot of things from a real Lisp will be missing, but I think there's enough to give you a sense of the core of the language. Actually, this version isn't too far off from the original Lisp written by John McCarthy over 55 years ago.
I don't really have a good answer as to how much experience is needed, but I do know I wish I had attempted it earlier.
My suggestion: Just try and see how it goes. If you find it too overwhelming, don't worry, you can always revisit the concepts later.
I didn't write the tutorial with novice programmers in mind, so I can't promise everything will be explained as you need. But still, if you do try, I'd love to hear your experiences.
It's definitely a journey! And I agree that trying to figure out how the concepts for yourself is by far the most rewarding. I hope this tutorial can help people realize that it's not difficult to get started, and inspire them to get started exploring on their own.
