 Both the argument and the return value are serialized with [devalue](https://github.com/sveltejs/devalue), which handles types like `Date` and `Map` (and custom types defined in your [transport hook](hooks#Universal-hooks-transport)) in addition to JSON.

 ## query.batch
 
 `query.batch` works like `query` except that it batches requests that happen within the same macrotask. This solves the so-called n+1 problem: rather than each query resulting in a separate database call (for example), simultaneous queries are grouped together.

+### Updating queries after form submissions
 
 By default, all queries used on the page (along with any `load` functions) are automatically refreshed following a successful form submission. This ensures that everything is up-to-date, but it's also inefficient: many queries will be unchanged, and it requires a second trip to the server to get the updated data.

 ## prerender
 
 The `prerender` function is similar to `query`, except that it will be invoked at build time to prerender the result. Use this for data that changes at most once per redeployment.
