You can use the plain Object.getPrototypeOf() check here, that should give better performance in the common case and won’t hurt

I guess it might depend on how you pronounce it, but isn’t it a Uint8Array?

As long as the error message is being changed, it would be better to make it more consistent ...

e.g.

"buffer" must be a string, Buffer, or Uint8Array

Yeah I was thinking of "unsigned 8-bit integer array" which would indeed be "an". @jasnell's suggestion looks better though.

@addaleax, @jasnell comments addressed; PTAL.

I think there should be a space before and after |.

The docs are inconsistent - sometimes spaces, sometimes not - but no spaces appears to be commonest.

Ping @nodejs/ctc, this needs one more approval

Style nits but nothing major. The only thing that baffles me is the way the 'is buffer?' check is performed.

We don't use × anywhere else in the documentation.

What do you suggest?

Just the 16*1024 that was there before.

Can you wrap the body in braces? Why the contorted Object.getPrototypeOf() and instanceof check?

@bnoordhuis I believe it’s because instanceof can be quite slow, so in the exceedingly common case the getPrototypeOf check suffices. But you’re right, I’d just drop the instanceof part.

Teeny-tiny style nit: four space indent.

Also support Uint8Array as a `dictionary` option.
