Yes, JavaScript also has a single namespace, like a Lisp-1. The advantage of a Lisp-2 is that it makes macro writing easier; you can include calls to known functions in the expansion without having to deal with the possibility that those names have been shadowed. |

A variable foo, referenced as $foo, has nothing do with a function foo called as "foo args ...".
Imagine how stupid it would be if assigning a variable called ls prevented the ls command from working.
