title: javascript number split
body: <p>Can anyboyd help me split up this date number in javascript so that when it is outputted to the screen it has slashes between the 4th and 5th number and the 6th and 7th number, so that it can be understood by a vxml voice browser. The number can be any value so i need it to work for any eight digit number.</p>
  
  <p>Like so:</p>
  
  <p>20100820</p>
  
  <p>2010/08/20</p>
  
  <p>Many thanks</p>
