Javascript is weakly typed. And untyped does not mean no type declarations. It means no types, just like it says. Assembly is untyped. Javascript is dynamically typed. Very different. http://en.wikipedia.org/wiki/Programming_language#Typed_vers... Javascript does not define the implementation details. It does not have to be interpreted, and in fact I don't believe any modern implementation is interpreted. Javascript is generally compiled to byte code which is then run in a VM, or native machine code (V8 at least does this). There is no reason javascript could not have a static type system, there are statically typed scripting languages. It is dynamically typed by deliberate decision, not "we can't do it any other way". |
