Is ruby strongly or weakly typed?

Question

Is ruby strongly or weakly typed ?

Presumably the same is true for Javascript.

Answer 1

Wikpedia labels it as "dynamic ('duck') typed".

Regarding Pop's comment about it being "strong-typed" - I'm not sure his explanation actually fits with what goes on under the covers. The MRI doesn't really "check" to see if an operation can be performed on an object; it just sends the object the message, and if that object doesn't accept that message (either by a method declaration or by handling it in #method_missing) it barfs. If the runtime actually checked to make sure operations were possible, #method_missing wouldn't work.

Also, it should be noted that since everything in Ruby is an object (and I do mean everything), I'm not sure what he said about "not in an oo-sense" is accurate. In Ruby, you're either an object or a message.
