An ECMAScript spec-compliant polyfill/shim for globalThis. Invoke its "shim" method to shim globalThis if it is unavailable.

This package implements the es-shim API interface. It works in an ES3-supported environment and complies with the spec proposal.

Most common usage:

var globalThis = require('globalthis')(); // returns native globalThis if compliant
	/* or */
var globalThis = require('globalthis/polyfill')(); // returns native globalThis if compliant

Example

var assert = require('assert');

// the below function is not CSP-compliant, but reliably gets the
// global object in sloppy mode in every engine.
var getGlobal = Function('return this');

assert.equal(globalThis, getGlobal());
/* when `globalThis` is not present */
var shimmedGlobal = require('globalthis').shim();
	/* or */
var shimmedGlobal = require('globalthis/shim')();

assert.equal(shimmedGlobal, globalThis);
assert.equal(shimmedGlobal, getGlobal());
/* when `globalThis` is present */
var shimmedGlobal = require('globalthis').shim();

assert.equal(shimmedGlobal, globalThis);
assert.equal(shimmedGlobal, getGlobal());
