Issue with "globalThis": ("the global across environments" content is outdated))

MDN URL: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/globalThis

What information was incorrect, unhelpful, or incomplete?

Prior to globalThis, the only reliable cross-platform way to get the global object for an environment was Function('return this')(). However, this causes CSP violations in some settings, so es6-shim uses a check like this, for example:

the global across environments content is outdated.

es6-shim source code is changed, for example:

var getGlobal = new Function('return this;');

This is because es6-shim and es6-sham are two things. You can find es6-shim's related source here: https://github.com/paulmillr/es6-shim/blob/c3eb45b440092c53597e092cee47cedb578f4c24/es6-shim.js#L176-L187

The idea of a sham is that—IIUC—it just provides the existence of an API, but does not provide any behaviors, so the implementation appears to be quite cracky.
