title: Getting n pairs from a sequence of strings
body: <p>Is there a method with javascript that can return <code>n</code> sequences of string that form a part of a larger string?</p>
  
  <p>For example, in a sequence like:</p>
  
  <pre><code>Paris, Italy, London, Perth, Moscow, Wellington
  </code></pre>
  
  <p>How could I get <code>n</code> word-pairs where n = 2 in this example. The output would be:</p>
  
  <pre><code>Paris, Italy
  London, Perth
  Moscow, Wellington
  </code></pre>
  
  <p>Is there a built in method with Javascript that could help me achieve this?</p>
