Note: do not merge until stage 4 - an approved PR is now a pre-stage-4 requirement.

For context, the name global has web compatibility issues. @ljharb is working on switching to a new name. This patch will not land in its current state.

FYI to TC39: there is an interesting question of what globalThis should be for discarded windows. (I.e. those whose parent iframe was .remove()ed, or whose window was .close()ed.) It appears Chrome/Safari/Firefox all continue to return the global object in that case. However, for self/window/frames, Safari returns null instead.

@annevk filed a bug on Safari to align their window/self/frames with Chrome/Firefox, and also with their own globalThis implementation.

So, there is no action here for TC39, but I thought it'd be interesting to know.

this phrasing is super awkward. Any recommendations of how to do this cleaner without algorithm steps?

<p>The initial value of `globalThis` is the value of the field of (the value of the field of the Realm Record named [[GlobalEnv]]) named [[GlobalThisValue]].
<p>The initial value of the `globalThis` property of the global object of a realm _realm_ is the value of `_realm_.[[GlobalEnv]].[[GlobalThisValue]]`.</p>

That fudges the distinction between a realm and a Realm Record, so you could say ... of a realm represented by the Realm Record _realm_ ..., but I'm doubtful that'd be better.
