- Update library to include ES.next support for `Map`, `Set`, `ArrayBuffer`. Part of #36 - Update to `fast-deep-equal@3.1.1` with modified support for ES.next data types. - Upgrade lots of `devDependenices` - Use `fast-deep-equal` tests directly in our correctness tests. - Update CI to modern Node.js versions. - **Note**: There's a bug / limitation of `Set` comparisons whereby objects are compared by reference not value. Tracked at #50 . In our `yarn benchmark`, `lodash.isEqual` gets test differences because it correctly handles those.
