title: Correct way to initialize empty slice
body: <p>To declare an empty slice, with a non-fixed size,
  is it better to do:</p>
  
  <pre><code>mySlice1 := make([]int, 0)
  </code></pre>
  
  <p>or:</p>
  
  <pre><code>mySlice2 := []int{}
  </code></pre>
  
  <p>Just wondering which one is the correct way.  </p>
