List.TransformMany(list as list, collectionTransform as function, resultTransform as function) as list
Returns a list whose elements are projected from the input list. The
collectionTransform function is applied to each element, and the
resultTransform function is invoked to construct the resulting list. The
collectionSelector has the signature (x as Any) => ... where x is an element in list. The
resultTransform projects the shape of the result and has the signature (x as Any, y as Any) => ... where x is the element in list and y is the element obtained by applying the
collectionTransform to that element.
