Well, it seems to me that Typed Arrays is the right way to go about implementing ByteArray in JS.[1]
IIUC, mimicking ByteArray is the hardest part of AMF. Of course, this means a minimum of IE10, but that might be OK… [1]https://developer.mozilla.org/en-US/docs/Web/JavaScript/Typed_arrays On Dec 1, 2015, at 8:25 PM, Alex Harui <aha...@adobe.com> wrote: > > > On 12/1/15, 10:18 AM, "Christofer Dutz" <christofer.d...@c-ware.de> wrote: > >> Well actually it sounded like: We had AMF support, but it didn't perfrom >> as well so we threw it away ... >> > > No, nobody I know has worked on it.
