slice

Details

‘⁠sliceArray⁠’ builds an extractor string containing the value of ‘⁠slice⁠’ as the first element and as many commas as needed to match the dimensions of the array. It then applies the extractor function to ‘⁠x⁠’ and returns the result. Note how the array "slice" swaps dimensions in the example.

Value

The desired slice of the array.
