JavaScript

// Simulate old browser
let defaultGlobalThis = globalThis;
globalThis = null;
console.log(globalThis); // null

// Apply shim
(typeof globalThis!="object"||!globalThis||globalThis.Math!==Math||globalThis.Array!==Array)&&(typeof self<"u"?globalThis=self:typeof window<"u"?globalThis=window:globalThis=Function("return this")());

// Did it work?
console.log(globalThis); // not null (Window)
console.log(globalThis === defaultGlobalThis); // should be true
