title: first backword letter is always undefined
body: <pre><code>function spinWords(string){
    var backwords = [];
  
    regex = /\b[a-zA-Z]{5,}\b/g
    var fiveletter = string.match(regex);
    for (let i = 0; i&lt;fiveletter.length; i++)
      for (let t=fiveletter[i].length; t--;)
        backwords[i] += fiveletter[i][t]; 
  
    return backwords;
    //TODO Have fun :)
  }
  </code></pre>
  <p>when i printout fiveletter[i][t] i dont have undefined however when i added to my backwords[i] array, the first char is always undefined. Can anyone explain why that is?</p>
  <p>Thanks</p>
