A frequent use case when transducing is to apply a transformation to items without changing the type of the collection.

In this lesson, we'll create a helper to do just that. seq will be similar to into, except the target type will be inferred from the source collection. For example, if transducing from an array, seq will create an array as the output collection as well.

seq is thus more restrictive and easier to consume than into.
