objectDiff

objectDiff.diff(objectA, objectB)

objectDiff.diff({x: 1}, {x: 2})
-> {
  changed: "object change",
  value: {
    x: {
      changed: "primitive change",
      removed: 1,
      added: 2
    }
  }
}

objectDiff.diff({z: {x: 1}}, {z: {y: 2}})
-> {
  changed: "object change",
  value: {
    z: {
      changed: "object change",
      value: {
        x: {
          changed: "removed",
          value: 1
        },
