You can't learn a programming language like that, unless it already has very similar paradigms to languages you already know. For example, try to learn APL[1] or Haskell like that (or just assembly if you haven't done any kind of assembly yet).

[1] And that's not just because of the arcane symbols.

I think assembly is probably the one language family you'd find most success learning from a reference sheet.

Once you've been told what a register, a stack, and an addressing mode is (among other details), sure. But then you do know the paradigms already.

But of the languages I mentioned, assembly is certainly the one where the required concepts can be explained quickest, probably by far...

Yeah, sure - as long as that reference sheet is the CPU reference manual.
