# # `merge()`

The merge method merges the given object into the original collection. If a key in the given object matches a key in the original collection, the given objects value will overwrite the value in the original collection:

    const collection = collect({
      id: 1,
      price: 29
    });

    const merged = collection.merge({
      price: 400,
      discount: false
    });

    merged.all();

    //=> { id: 1, price: 400, discount: false }

If our collection is an array, the values will be appended to the end of the collection:

    const collection = collect(["Unicorn", "Rainbow"]);

    const merged = collection.merge(["Sunshine", "Rainbow"]);

    merged.all();

    //=> ['Unicorn', 'Rainbow', 'Sunshine', 'Rainbow']
