Question on HelixQL

[LikeCrazyShawn]

I am reading the helixQL webpage and have below questions.

1. Adding Nodes and Edges

the second line of code should be as below right?
user2 <- N::AddE::From(N(user2ID))

and where is the friendship?

QUERY CreateFriendships(user1ID: String, user2ID: String) =>
// This makes every user in the database follow the user with ID user1ID
user1 <- N::AddE::To(N(user1ID))

// This makes user with userID2 follow every user in the database
user1 <- N::AddE::From(N(user1ID))

RETURN friendship

2. Traversals from Nodes
   what's the difference between Out and OutE? I didn't find any details from the GetFollowingDetails query.
   QUERY GetUserFollowing(userID: ID) {
   following <- N(userID)::Out
   RETURN following
   }
   QUERY GetFollowingDetails(userID: ID) {
   following <- N(userID)::OutE
   RETURN following
   }

you don't have to use N(user1ID)

you would just do
user1 <- AddE<EdgeType>::From(user1ID)::To(user2ID)

the difference between Out and OutE is that Out returns the nodes that the outgoing edges point to. OutE returns the outgoing edge (not the nodes).
