• where
• orderBy
• thenBy
• distinct
• groupBy
• groupJoin
• join
• except

  Examples
  A simple example of breaking up a sequence of numbers into even and odd arrays:
  
  var list = $linq([1, 2, 3, 4, 5, 6, 7, 8, 9, 10]);
  
  var evens = list.where(function (x) { return x % 2 == 0; }).toArray();
  var odds = list.where("x => x % 2 == 1").toArray();
