Node 12 and apple silicon arm64

[kessk]

Hi team, I have node 12.22.5 installed on my Apple Silicon macbook as some constraints are preventing me from making the leap to 15.x/16.x. Node was installed using nvm.

Without ever purposefully invoking Rosetta, which I can confirm since terminal arch returns arm64, I noticed that going into Node and invoking process.arch returns x64. Now, from what I understand, this can only mean that I am running node with the compatibility layer (Rosetta).

1. Is my understanding correct that Node automatically uses Rosetta for the user? I was under the impression that I would have had to manually run arch -x86_64 ... into the terminal to invoke Rosetta.
2. doesitarm website says Node 12 has native apple silicon support. However, I do not see anything on the Node website indicating this. On the release notes, the only hint I can get is this commit. Is the doesitarm entry wrong? I would think that I would be able to get arm64 from process.arch had it been the case.
