This example illustrates how to use the nested functions. |

**Functions**:

**Source:**

Code formatting has been applied to improve legibility.

Item | ArrayA | ArrayB |
---|---|---|

Item1 | `["A","B","C"]` | `["1","2","3"]` |

Item2 | `["A","B"]` | `["A","B","C"]` |

Item3 | `["D","E","F"]` | `["4","5","6"]` |

**Transformation:**

You can apply the following transforms in the following order. Note that the column names must be different from the transform name, which is a reserved word.

**Results:**

For display purposes, the results table has been broken down into three separate sets of columns.

Column set 1:

Item | ArrayA | ArrayB | concat2 | intersection2 |
---|---|---|---|---|

Item1 |
| `["1","2","3"]` | `["A","B","C","1","2","3"]` | `[ ]` |

Item2 | `["A","B"]` | `["A","B","C"]` | `["A","B","A","B","C"]` | `["A","B"]` |

Item3 | `["D","E","F"]` | `["4","5","6"]` | `["D","E","F","4","5","6"]` | `[ ]` |

Column set 2:

Item | cross2 |
---|---|

Item1 | `[["A","1"],["A","2"],["A","3"],["B","1"],["B","2"],["B","3"],["C","1"],["C","2"],["C","3"]]` |

Item2 | `[["A","A"],["A","B"],["A","C"],["B","A"],["B","B"],["B","C"]]` |

Item3 | ```
[["D","4"],["D","5"],["D","6"],["E","4"],["E","5"],["E","6"],
["F","4"],["F","5"],["F","6"]]
``` |

Column set 3:

Item | unique2 |
---|---|

Item1 | `["A","B","C","1","2","3"]` |

Item2 | `["A","B","C"]` |

Item3 | ```
["D","E","F","4","5","6"]
``` |
