  }
}

const object2 = {
  key: 'value',
  baz: [4, 5, 6],
  nestedObject: {
    also: 'this value overrides the one from object1 due to this object having priority',
    anotherKey: 'anotherValue'
  }
}

// Returns the resultingObject below
merge(object1, object2, {
  priorityObject: 'right',
  useStructuredClone: true,
  mergeArrays: true
})

const resultingObject = {

  baz: [1, 2, 3, 4, 5, 6],
