Actually it IS valuable to have some understanding of assembler, even when you are using JavaScript on a daily basis. Maybe it's not that important for a beginner programmer now, since source maps are available, but I would encourage everyone to go as low-level as possible. Some JS and CS constructs have an awful representation underneath. Think of eval, dynamic types or hashtable-like objects.
