# # `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 };
