Custom Predicates

You can create your own predicates for reusability and better readability:
// SYNTAX
predicate_name :- predicate_body
​
// EXAMPLE
get_token_owner(OwnerAddress) :- 
  call_fn(hyperdapp, owner, [OwnerAddress]).
​
prompt :-
  get_token_owner(OwnerAddress),
  show [
    text('Welcome ', OwnerAddress)
  ].
The output value of theownermethod is stored in the OwnerAddressvariable. To expose this value outside of your predicate, we just need to add it as an input.
