What are the downsides of using immutable state?

The main downsides include increased memory usage and potential performance hits during large state updates, as new copies of the state are created.

How can I implement immutable state in my application?

You can use libraries like Immutable.js or Immer, or simply use JavaScript's spread operator to create shallow copies of your state.
