append!

..  append!(collection, collection2) -> collection.

Add the elements of ``collection2`` to the end of ``collection``.

.. doctest::

   julia> append!([1],[2,3])
   3-element Array{Int64,1}:
    1
    2
    3

.. doctest::

   julia> append!([1, 2, 3], [4, 5, 6])
   6-element Array{Int64,1}:
    1
    2
    3
    4
    5
    6

Use :func:`push!` to add individual items to ``collection`` which are not
already themselves in another collection.
The result is of the preceding example is equivalent to
``push!([1, 2, 3], 4, 5, 6)``.

Examples

julia> foo = [1];
julia> append!(foo, [2,3]);             # contrast with push!

julia> foo
3-element Array{Int64,1}:
 1
 2
 3

julia> a= [1, 2, 3]
       b = [4, 5, 6]
       append!(a,b)
6-element Array{Int64,1}:
 1
 2
 3
 4
 5
