Iterating on data (for)

FOR is the primary construct used for iterating over a collection and its documents. You can use for to iterate over collections and apply filters or additional processing on the data

Basic for

1. Here is an example of returning any 100 documents

   for flight in flights
       limit 100
       return flight

2. Here is an example of deleting all the documents we created in the scratch collections (the return OLD returns the the deleted documents)

   for junk in scratch
       remove junk in scratch
   return OLD._key

3. Running the AQL query again will return an empty list

   []
