My solution to Roller Coaster Text Exercise

[Ming Wei]

var text = 'Hello World!';

var div = document.getElementById('rollercoaster');

for (var i = 0; i < text.length; i++) {

  var fontSize = 10 + 5 * (Math.min(i, text.length - i - 1));

  var currentNode = document.createElement('SPAN');

  currentNode.appendChild(document.createTextNode(text[i]));

  currentNode.style.fontSize = fontSize + 'px';

  div.appendChild(currentNode);

}
