title: Number combination calculating
body: <p>I have a task where I need to generate all possible combination of numbers from 0-0-0 to
  100-100-100 (x,y,z)</p>
  <pre><code>var x = 0
  
  var y = 0
  
  var z = 0
  
  while(true){
  x++
  while(true){
      y++
      while(true){
         z++
         msg.payload = [x,y,z]
         node.send(msg)
          }}}
  </code></pre>
  <p>The problem I have is that the x and y values never change (only once when input)...
  I think this is not an efficient way of doing this, any suggestion?</p>
