When rendering `Page`, the component calls <CodeStep step={1}>`getUser`</CodeStep> but note that it doesn't use the returned data. This early <CodeStep step={1}>`getUser`</CodeStep> call kicks off the asynchronous database query that occurs while `Page` is doing other computational work and rendering children.
When rendering `Profile`, we call <CodeStep step={2}>`getUser`</CodeStep> again. If the initial <CodeStep step={1}>`getUser`</CodeStep> call has already returned and cached the user data, when when `Profile` <CodeStep step={2}>asks and waits for this data</CodeStep>, it can simply read from the cache without requiring another remote procedure call. If the <CodeStep step={1}> initial data request</CodeStep> hasn't been completed, preloading data in this pattern reduces delay in data-fetching.
