// merge both objects into one
const objectC = smartMerge(objectA, objectB, {
  matchSimilarKeys: false,
  cloneObject: true,
  prioritizedKeys: [
    ['apiVersion', 'kind', 'metadata.name', 'metadata.namespace'], // prioritize items that have all of the defined keys and all keys are the same

  ],
});

Options
