section numbers tend to change, i'd just say "as defined in the ecmascript language specifiation."

[lundibundi]

This looks like a good idea but a lot of the other functions (in this doc) have links to the appropriate sections in the spec so I'm not sure.

Wow, another ICE here

Hm, ICE on debian9-docker-armv7 once again, not sure how to fix that.

/cc @nodejs/n-api @addaleax perhaps you can help?

[addaleax]

@lundibundi Somewhere @bnoordhuis suggested that those ICEs might be the result of an out-of-memory situation … I think it’s a machine that doesn’t have a ton of memory, so that might make sense?

LGTM once my suggestion addition of the stability is added.

This needs a backport to land on v12.x-staging because V8 7.8 doesn't have ArrayBuffer::GetBackingStore
