+### Mapping props from mapper
 
 Sometimes get properties from your mappers can be kind a boring depending how nest is the result from each mapper. To easily avoid deep nested objects or combine your results, you can map the final results into a single object using de `mapProps` function as second parameter.

 ### Leading with multiple params
 
 Some render props components return multiple arguments in the children function instead of a single one (see a simple example in the new [Query](https://www.apollographql.com/docs/react/essentials/queries.html#basic) and [Mutation](https://www.apollographql.com/docs/react/essentials/mutations.html) component from `react-apollo`). In this case, you can do an arbitrary render with `render` prop [using your map value as a function](#custom-render-and-retrieving-props-from-composed):
