I am using JavaScript Evaluator processor in my pipeline and I would like programmatic access to each record field and its values in a loop. How can I achieve that?

You can use the following JavaScript code to iterate through each record (field,value) pair:

for(var i = 0; i < records.length; i++) {
  try {
    // Access each record field and its value    
    var record_dictionary = records[i].value;
    for (var field in record_dictionary)  {
      var field_value = record_dictionary[field];"=== field: {} | value: {}",field,field_value);

      // do something... 

    // Write record to processor output
  } catch (e) {
    // Send record to error
    error.write(records[i], e);
