That's semantics. He didn't get the "basic stuff wrong in a single paragraph" at all. Bu not having to worry about pointer or memory allocation at the the point of coding, it is entirely reasonable to say that JS the language has none. Yes, of course the interpreter does that, it goes without saying. JS is weakly typed, when writing no type declaration is needed, so it is said that JS isn't typed. Your comment is akin to that of a grammar pedant by not addressing the argument, just the manner in which the points were made.
