echo '{"sizes": ["S", "M", "L"], "colors": ["red", "blue"]}' \
  | utlx -e 'crossJoin($input.sizes, $input.colors)'
# [["S","red"],["S","blue"],["M","red"],["M","blue"],["L","red"],["L","blue"]]

{
  variants: map(crossJoin($input.sizes, $input.colors), (pair) -> {
    size: pair[0], color: pair[1]
  })
}
