5. - Variables - v2.md

1. Returns a query for the given variables. The query won't execute if the variables aren't provided.

   Person = Person:$LastName/$FirstName
   {
       FirstName = @node(),
       LastName = \#FamilyName,
       NickName,
       Friends[] = /Friends/
       {
       }
   }
   

2. Mutations can also use variables.

   Person = @node-add(Person:$lastName/, $firstName)
   {
       string NickName = $nickName
   }
