It targets a virtual machine, not a physical one, but other than that it's "assembly-like" enough that learning some core ASM coding practices will help you.
Not sure why you are sticking to your guns here. First, it's highly unlikely anyone would ever write wasm by hand. Second, the article rambles a bit but the most compelling argument for assembly is writing fast code for constrained hardware. At a high level, that's not what wasm is solving.
