List Value

ListValue [Const] :
   []
   [Value [?Const] list]

Lists are ordered sequences of values wrapped in square‐brackets[ ]. The values of a List literal may be any value literal or variable (ex.[1, 2, 3]).

Commas are optional throughout GraphQL so trailing commas are allowed and repeated commas do not represent missing values.

Semantics

ListValue : []
   Return a new empty list value.
ListValue : [Value list]
   Let inputList be a new empty list value.
   For each Value list
      Let value be the result of evaluating Value.
      Append value to inputList.
   Return inputList
