::{
    <new_property>: <schema_field>,
    <computed_property>: <traversal_expression>
}
Property additions allow you to compute derived values and add metadata to your query results without modifying the underlying schema.
When using the SDKs or curling the endpoint, the query name must match what is defined in the queries.hx file exactly.

​
Example 1: Adding computed properties with traversals

QUERY GetUserDetails () =>
    users <- N<User>::RANGE(0, 5)
    RETURN users::{
        userID: ID,
        followerCount: _::In<Follows>::COUNT
    }

QUERY CreateUser (name: String, age: U8) =>
    user <- AddN<User>({
        name: name,
        age: age
    })
    RETURN user

QUERY CreateFollow (follower_id: ID, following_id: ID) =>
    follower <- N<User>(follower_id)
    following <- N<User>(following_id)
    AddE<Follows>::From(follower)::To(following)
    RETURN "Success"
Here’s how to run the query using the SDKs or curl 
from helix.client import Client

client = Client(local=True, port=6969)

users = [
    {"name": "Alice", "age": 25},
    {"name": "Bob", "age": 30},
    {"name": "Charlie", "age": 28},
    {"name": "Diana", "age": 22},
]

user_ids = []
for user in users:
    result = client.query("CreateUser", user)
    user_ids.append(result[0]["user"]["id"])

for i in range(1, len(user_ids)):
    client.query("CreateFollow", {
        "follower_id": user_ids[i],
        "following_id": user_ids[0]
    })

result = client.query("GetUserDetails", {})
print("User details with follower count:", result)
