That's why it's such an important first language! Pedagogically it's the foundation motivating all the fancy things languages give you.
You don't teach a kid to cut wood with a table saw. You give them a hand saw!
Programming languages are usually designed based on formal semantics. They include constructs that have been found either through experience or certain formal reasons to be good ways to structure programs.
Haskell's lazy evaluation model, for example, has no relationship to assembly code. It was not in any way designed with thought to how assembly code works, it was designed to have certain desirable theoretical properties like referential transparency.
It's also important to realize that there is no "assembly language". Each processor family has its own specific assembly code with its own particular semantics that may vary wildly from any other processor. Not to mention, there are abstract assembly codes like WebAssembly or JVM bytecode, which often have even more alien semantics.
You don't teach Haskell to seventh grader.
But 4 bit assembly driving a few LEDs? That works
But hey, what do I know. Im the kind of guy who gets to play with TMA and seriously considers purchasing hydrazine for work. What do I know?
Okay but that's not for pedagogical reasons, it's because power saws are MUCH more dangerous than hand saw.
Contrariwise, you don't teach a kid to drill wood with a brace & bit, because a power drill is easier to use.
