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:
js
var globalThis = require('globalthis')(); // returns native globalThis if compliant
/* or */
var globalThis = require('globalthis/polyfill')(); // returns native globalThis if compliant
```js 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()); ```
``js
/* whenglobalThis` is not present /
var shimmedGlobal = require('globalthis').shim();
/ or */
var shimmedGlobal = require('globalthis/shim')();
assert.equal(shimmedGlobal, globalThis); assert.equal(shimmedGlobal, getGlobal()); ```
``js
/* whenglobalThis` is present */
var shimmedGlobal = require('globalthis').shim();
assert.equal(shimmedGlobal, globalThis); assert.equal(shimmedGlobal, getGlobal()); ```
