The WeakRef and FinalizationGroup polyfill/sham *
- CDN global patch via https://unpkg.com/@ungap/weakrefs
- ESM via
import {WeakRef, FinalizationGroup} from '@ungap/weakrefs' - CJS via
const {WeakRef, FinalizationGroup} = require('@ungap/weakrefs')
* The implementation uses WeakMap and it does not actually trigger the FinalizationGroup callback, unless explicitly asked via fg.cleanupSome(fn).
If you have issues just requiring @ungap/weakrefs, be sure you require @ungap/weakrefs/cjs instead.
No issue should happen if you just import the module instead.
