You are working on optimizing a large React application. Part of the optimization involves ensuring that certain components are only loaded when they are needed. What technique would you apply?

To optimize a large React application and load components only when needed, you would typically use code-splitting with dynamic imports. This technique allows you to split your bundle into smaller chunks and load them on-demand. useMemo() is used for memoization, Redux is for state management, and server-side rendering is a different optimization technique not directly related to lazy loading components.
