// TypeScript v4.4.4 doesn't support `node16` or `nodenext` in
// [Module Resolution](https://www.typescriptlang.org/tsconfig#moduleResolution)
// which is required for typescript to resolve the `package.json#exports`
// entries.
// Additionally, using `node16` or `nodenext` in `tsconfig.json#moduleResolution`
// requires the TypeScript to generate ESModule outputs. This is a breaking
// change for CJS users.
// So we have to use plain JavaScript to verity the `package.json#exports` here.
