How can I optimize performance in a React-Redux application using TypeScript?

To optimize performance, consider using memoization with React.memo and useMemo, and also implement selectors with Reselect.

What are selectors and how do they help with performance?

Selectors are functions that extract and compute derived state from the Redux store. They help by preventing unnecessary re-renders.

Can you give an example of a selector?

Sure! A simple selector could be const getVisibleTodos = (state) => state.todos.filter(todo => !todo.completed);.

How does TypeScript improve the development experience in this context?

TypeScript provides type safety, which helps catch errors early and improves code readability, making it easier to manage complex state.
