existence of globalThis

[frank-dspeed]

The existence of globalThis is agreed on by the spec and it should exist in all environments as it is a reaction to the following problem:

• global variable name can not clear be detected while it always exists by the standard there is no single ecmascript compatible environment possible without a global scope no matter which name it is assigned to.

why

it got questioned and i want to give my 5cent as representant of 4 engines and 2 languages where it is the case that it always exists

This is not something we have to call out explicitly, as the existence of globalThis is already something that all conformant ECMA262 implementations must have already.

@lucacasonato then i missreaded the notes in the last meeting how should i interpret that ? It reads for me like it is qestioned if we should assume the existince of globalThis

- Should globalThis be there at all? Is that more a part of the language
       spec?

and i wanted to make clear it is part of the language spec and is not even avoid able for none engine authors.
