Handling Arrays of Data

The Wolfram Language routinely handles huge arrays of numeric, symbolic, textual, or any other data, with any dimension or structure. Arrays are fully integrated into the Wolfram Language, making possible extremely high-level array operations that are both elegant and efficient.
