  You can perform this type of operation with a field hook. Here is an example of a beforeChange hook to populate a

  firstName

  field by splitting the

  fullName

  value.

  
  
  

      {
        name: 'fullName',
        type: 'text',
        hooks: {
          beforeChange: [
            ({ data, value, operation }) => {
              data.firstName = typeof value === 'string' ? value.split(' ')[0] : '';
              return value;
            },
          ],
        },
      },
      {
        name: 'firstName',
        type: 'text',
      },
