While much of performance deals with what you can do to optimize and eliminate unnecessary resources, it may seem a bit paradoxical to suggest that some resources should be loaded before they're needed. However, there are some cases in which it _might_ be appropriate to load certain resources ahead of time. In this module, this aspect of performance is explored, as prefetching and prerendering are discussed.| web.dev
