PK cT[�%��Z Z README.mdnu ȯ�� # `scheduler` This is a package for cooperative scheduling in a browser environment. It is currently used internally by React, but we plan to make it more generic. The public API for this package is not yet finalized. ### Thanks The React team thanks [Anton Podviaznikov](https://podviaznikov.com/) for donating the `scheduler` package name.
