Selectors in NgRx are pure functions used to select a slice of state from the store. They help in optimizing performance.

Can you give me an example of a selector?

How do I combine multiple selectors?

You can use the createSelector function from NgRx. For example: const combinedSelector = createSelector(selectFeature, selectAnotherFeature, (feature, another) => { return { feature, another }; });
