Use new ES6 feature: [...new Set( [1, 1, 2] )];

function uniqueArray0(array) {

  var result = Array.from(new Set(array));

  return result    

}

Use filter + indexOf

function uniqueArray3(a) {

  function onlyUnique(value, index, self) { 

      return self.indexOf(value) === index;

  }

  // usage

  var unique = a.filter( onlyUnique ); // returns ['a', 1, 2, '1']

  return unique;

}
