Most Redis commands take one or more Strings as arguments, and replies are sent back as a single String or an Array of Strings. However, sometimes you may want something different. For instance, it would be more convenient if the HGETALL command returns a hash (e.g. { key: val1, key...
Data arrays are returned by most Dataview APIs that can return multiple results, such as dv.pages(). You can also explicitly convert a normal JavaScript array into a Dataview array using dv.array(<array>). If you want to convert a Data array back to a normal array, use DataArray#array...
