Nested data

Collections that hold other collections, like a list of rows for a grid - how a program stores tables, boards and structured records.

Depth 1 · Foundation

You can store a grid as a list of lists, reach an item with two indexes, loop over rows and columns, build rows that don't share one list, and read data shaped as collections inside collections.
