supposedly hot take - polyfills don't fucking belong in libraries this has been discussed [as back as 2017](https://github.com/w3ctag/polyfills/issues/6), yet somehow people like ljharb still exist and people keep falling for his "supporting node 0.4" premise. he is THE reason the web is such a bloat, smh if you *need* to support older envs - you polyfill/desugar shit yourself the only recent thing in js i know of that can't really be polyfilled are bigints (primarily bc they have their own `typeof` and work with math operators), but most of the other apis **can** and **should** be polyfilled, *by the app*.
