3.29A more realistic reusable function

Say several fields need defaults:

%dw 2.0
output application/json

fun clean(value) =
    trim(value default "")

---
{
    FirstName: clean(payload.firstName),
    LastName: clean(payload.lastName),
    Company: clean(payload.company)
}

This is much cleaner than performing each manipulation through Mule processors.
