for the vast majority of modern projects, you don't need the performance that manual memory management provides. I would bet that 90%+ of modern software is written in a memory-managed language. If you need to leap from JS to C, it's really not that hard. But trying to learn about stack frame allocation and RAII and cache line optimisation is a lot to take on when you've just learned what a variable is.

The abstractions are what's important, memory layout is an implementation detail. Even when you're writing C or assembly, you're still thinking in terms of data flow and logic, you're just having to do a lot of the work manually. Learning the abstractions without the baggage of the implementation detail will get 90% of people 90% of the way. Once you have that solid foundation, you can go on to learn assembly or C if you need it because it's not that big a leap from a coding mindset to a hardware control mindset. But to go straight from no coding experience to hardware control is going to be more difficult for a new student to wrap their head around.
