How can I use reselect with complex selectors?

Can you explain how to use reselect with complex selectors in my Redux application?

Sure! Reselect is a library for creating memoized selectors in Redux. Complex selectors can be created by combining simple selectors.

What are some examples of complex selectors I can create?

You can create selectors that derive data from multiple slices of state or apply transformations to the data, like filtering or sorting.

How do I ensure my selectors are efficient?

To ensure efficiency, use memoization provided by reselect, which caches the results of selectors based on their input.

Can you show me a code example of a complex selector?

Absolutely! Here's a simple example: const getVisibleTodos = createSelector([getTodos, getVisibilityFilter], (todos, filter) => {...});
