globalThis ponyfill

This is a trivial TypeScript-compatible globalThis ponyfill.

• very small minzipped size
• NO dependencies
• doesn't alter the environment (ponyfill)
• compatible with 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.
• 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
  • a ponyfill is better than a polyfill, it doesn't patch the environment.

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".
