title: How to split a slice in Go in sub-slices
body: <p>I'm recently using Go to create applications. My question is this: at a certain point in the program I have a string slice:</p>
  
  <pre><code>my_slice = []string{"string1","string2","string3","string4","string5","string6"}
  </code></pre>
  
  <p>It contains 6 strings. Which is the best procedure (easier to write and understand) to break this slice into 3 parts, for example, and distribute the content in three sub-slices?
  If I have:</p>
  
  <pre><code>var my_sub_slice1 []string
  var my_sub_slice2 []string
  var my_sub_slice3 []string
  </code></pre>
  
  <p>I wish at the end of it <code>my_sub_slice1</code> will contain (in his first two entries) <code>"string1","string2"</code>; <code>my_sub_slice2</code> will contain (in his first two entries) <code>"string3","string4"</code>; <code>my_sub_slice3</code> will contain (in his first two entries) <code>"string5","string6"</code>.
  I know the question is easy but I haven't found a clean and efficient way to do this yet.
  Thanks a lot!</p>
