Utility Functions #

The Redux core exports additional utility functions for reuse.

isAction #

Returns true if the parameter is a valid Redux action object (a plain object with a string type field).

This also serves as a TypeScript type predicate, which will narrow the TS type to Action<string>.

isPlainObject #

Returns true if the value appears to be a plain JS object.
