zip
Combines two lists into a list of pairs.
zip(xs:list, ys:list) -> listDescription
The zip function returns a list containing records with two fields left and
right, each containing the respective elements of the input lists.
If both lists are null, zip returns null. If one of the lists is null or has a
mismatching length, missing values are filled in with nulls, using the longer
list's length, and a warning is emitted.
Examples
Combine two lists
from {xs: [1, 2], ys: [3, 4]}
select zs = zip(xs, ys)
{
zs: [
{left: 1, right: 3},
{left: 2, right: 4}
]
}
