firstKey

Returns the first key found on an object from a list of keys

Example

    var obj = {
        word1: 'The',
        word2: 'quick',
        word5: 'jumped',
        word8: 'lazy'
    },
    
    key = firstKey(obj, 'word3', 'word5', 'word7');  // First key found is 'word5'

Pull the first property from a dom node that exists and reuse that property

• Choosing the text property to use

   var div = document.createElement('div'),
       text = firstKey(div, 'textContent', 'innerText', 'innerHTML');
          
   div[text] = 'Let\'s use the best property for setting the text';

• Identifying the vendor-specific property to use, so that you don't set them all needlessly

   var divElement = document.createElement('div'),
      
   transformProperty = firstKey(
       divElement.style,
       'transform',
       'webkitTransform',
       'MozTransform',
       'oTransform',
       'msTransform');
  
   transformOriginProperty = firstKey(
       divElement.style,
       'transformOrigin',
       'webkitTransformOrigin',
       'MozTransformOrigin',
       'oTransformOrigin',
       'msTransformOrigin');
