# # `concat()`

The concat method is used to merge two or more collections/arrays/objects:

You can also `concat()` an array of objects, or a multidimensional array

    const collection = collect([1, 2, 3]);

    let concatenated = collection.concat(["a", "b", "c"]);

    concatenated = concatenated.concat({
      name: "Steven Gerrard",
      number: 8
    });

    concatenated.all();

    //=> [1, 2, 3, 'a', 'b', 'c', 'Steven Gerrard', 8]
