concat

concat(string1, string2, ...) → string · String

Concatenate any number of strings.

string1, string2, ... (variadic): strings to concatenate

bash

echo '{"title": "Dr.", "firstName": "Alice", "lastName": "Johnson"}' \
  | utlx -e 'concat($input.title, " ", $input.firstName, " ", $input.lastName)'
# "Dr. Alice Johnson"

utlx

{
  fullName: concat($input.title, " ", $input.firstName, " ", $input.lastName),
  reference: concat("Order-", toString($input.orderId))
}

Anti-pattern: building long strings with reduce + concat. Use join(array, separator) instead.
