array buffers for binaries

[calvinmetcalf]

you could use array buffers for binary data.

I'm not that familiar with Javascript, but you seem to be on the money here :)

According to the Mozilla spec the use case of Javascript is exactly that of binaries in Erlang:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Typed_arrays

I'm sure being able to destructure binaries by pattern matching would be of interest to Javascript developers (presumably they currently do it by hand? or use CoffeeScript?).

How would we handle the bit syntax though?
http://www.erlang.org/documentation/doc-5.6/doc/programming_examples/bit_syntax.html

And do you want me to allocate this issue to you?

Also I have new policy of giving a rebar make_luvv t-shirt to all contributors:

destructive assignment is not in JavaScript yet, it's coming in es6, so currently done of that, but from what I remember of erlang (it's been a while) <<a,b,c>> is equivalent to javascript (new UintArray([a,b,c])).buffer;

meaning I'd want to add a line line like:

make_js(bin, {LNo, Bin}, OrigF, Acc) ->
    [{bin, "(new UintArray(" ++ binary_to_list(Bin) ++ ")).buffer", {OrigF, LNo}} | Acc];
