Cross-platform global variable detection with fallbacks

global-detection.js

// self is window proxy in IE<=10, eval handles this
var _global = (function () { try { return Function('return this')() } catch (e) {} })() // browsers without CSP, Node
  || typeof globalThis !== 'undefined' && globalThis // new and polyfilled browsers/workers CSP, newer Node with broken eval
  || typeof self !== 'undefined' && self // old browsers/workers with CSP
  || typeof global !== 'undefined' && global // old Node with broken eval
  || typeof window !== 'undefined' && window; // fallback for exotic environments
