globalThis ponyfill

This is a trivial TypeScript-compatible globalThis ponyfill.

• very small minzipped size
• NO dependencies
• doesn't alter the environment
• compatible node & browser

Usage

import { getGlobalThis } from '@offirmo/globalthis-ponyfill'
 
const globalThis = getGlobalThis()

Rationale

• globalThis is a TC-39 proposal which is already supported by Firefox and Chrome.
• a ponyfill is a better polyfill that doesn't patch the environment.

There are existing ponyfills/polyfills out there, but they didn't work for me:

• mine is much simpler: a single TS file of 6 meaningful lines
• I needed TypeScript

Credits

YES I had a look at ljharb/globalThis's implementation (MIT) and started my implementation from it! Thanks a lot and all credits due!

About the proposed implementation here: https://mathiasbynens.be/notes/globalthis we can't use it: it creates a polyfill, not a ponyfill. However I took a line from the "naive implementation".
