29. In what order will the numbers 1-4 be logged to the console when the code below is executed?

const a = { 
  stringField: 'Joe',
  nestedField: {field: 'Nested'}
};
const b = JSON.parse(JSON.stringify(a));
b.stringField = 'Bob';
b.nestedField.field = 'Changed';
console.log(
  a.stringField,
  a.nestedField.field
);
