diffAssoc()

The diffAssoc method compares the collection against another collection or a plain object based on its keys and values. This method will return the key / value pairs in the original collection that are not present in the given collection:

const collection = collect({
  color: "orange",
  type: "fruit",
  remain: 6
});

const diff = collection.diffAssoc({
  color: "yellow",
  type: "fruit",
  remain: 3,
  used: 6
});

diff.all();

//=> { color: 'orange', remain: 6 };
