title: Julia: append to an empty vector
body: <p>I would like to create an empty vector and append to it an array in Julia. How do I do that?</p>
  
  <pre><code>x = Vector{Float64}
  append!(x, rand(10))
  </code></pre>
  
  <p>results in</p>
  
  <pre><code>`append!` has no method matching append!(::Type{Array{Float64,1}}, ::Array{Float64,1})
  </code></pre>
  
  <p>Thanks.</p>
