WebAssembly global is not mentioned in documentation

[styfle]

• Version: 10.11.0
• Platform: all
• Subsystem: docs

It looks like the WebAssembly global is available but there is no mention in the docs of when this was introduced and which features are available.

Example usage: https://glot.io/snippets/f5j3smuum8

Should WebAssembly be added to the globals page or maybe even add a separate page?

[jasnell]

I think listing it in globals.md is good for now. We should likely have a dedicated page in the docs for it eventually tho.

we should just link to the mdn docs for it from globals.md

@devsnek Is the API 100% compatible? What about the streaming APIs such as WebAssembly.instantiateStreaming?

[thefourtheye]

This is perhaps good-first-contribution worthy?

[devsnek]

@styfle assuming we were to enable streaming compilation it would work. node and chrome use the same implementation from V8.

@devsnek From a quick test (and from the sound of your comment) the streaming compilation is not ready so the docs should make this clear. If/when that feature is enabled, then it can be added to the docs and the version can reflect when that shipped.

Speaking of which, at what version was the WebAssembly global added?

Speaking of which, at what version was the WebAssembly global added?

@styfle A quick test suggests it was 8.0.0.

$ node -v
v7.10.1
$ node -p 'typeof WebAssembly'
undefined
$ nvm use 8.0.0
Now using node v8.0.0 (npm v5.0.2)
$ node -p 'typeof WebAssembly'
object
$

@Trott Nice! That matches the MDN compatibility table.

I will create a PR to get this added to the globals and probably include a link to the MDN docs 👍
