Discussion on: JavaScript typed arrays: Unexpected overflow

Just because a language is specified different to C/C++ doesn't make it quirky. All of your example are just showing the specified behavior of any flavour of modern ECMAscript.

I would only consider this a quirk if the standard operators suddenly changed the specified behavior to handle typed arrays differently, i.e. if you assigned the result to another field of a Uint8Array and the results would differ or if assignments to untyped variables suddenly exposed the same overflow as the typed array ones.
