What do you mean by "across realms"?

Is that just another way of saying `Uint8Array.prototype.isPrototypeOf` and `instanceof Uint8Array` are not available in all JS environments?

I guess what I'm asking is the definition of a "Javascript Realm" in case I'm thinking it's something different.

Examples of this are frames in the browser and the `vm` module in Node.js.

Ah thanks, I thought "realms" sounded familiar and that helps clear things up a bit. Also Lavamoat and SES look really interesting thanks for the link.
