Converting Date to d/m/yyyy format

Scenario: Convert given date to the d/m/yyyy format

Solution:

You need to use the module ‘N/format‘ to convert the date to different formats. format.parse method can be use for this. It parses a value from the appropriate preference format to its raw value. The appropriate preference format is the one selected in the Date Format field at Home > Set Preferences. For a datetime or datetimetz value, use this method to convert a Date Object into a string based on the specified timezone.

The following is just an Example Syntax;

function getData(){
        var rec = record.load({
                         type: 'journalentry',
                         id: 2064, //You can change the record ID
                         isDynamic: true
                      })
       var transDate = rec.getValue({
                                fieldId: 'trandate'
                             })

       var initialFormattedDateString = convertDate(transDate);
       var parsedDateStringAsRawDateObject = format.parse({
                                        value: initialFormattedDateString,
                                        type: format.Type.DATE
                                    });
}
