Examples:
========================================================================================

    var data = [{x:1, y:5}, {x:3, y:7}, {x:5, y:9}, {x:7, y:11}, {x:9, y:13}];
    document.write('(' + data.select(a=>a.x + ',' + a.y).join('), (') + ')');

    output:
    (1,5), (3, 7), (5,9), (7,11), (9, 13)

  
  -----------------------------------------------

    var data = [{x:1, y:1}, {x:3, y:3}, {x:5, y:5}, {x:7, y:7}, {x:9, y:9}];
    var q = data.where(a=>a.x*a.y == 25).first();

    q's value:  
   {x:5, y:5} )
  
  -----------------------------------------------
  
    var data= [1, 5, 3, 9, 7];
    var str = data.orderAsc(a=>a).join(',');
  
    str's value:
   '1,3,5,7,9'
  
  ------------------------------------------------
  
  var data6 = [{x:1, y:6, z:3}, {x:1, y:5, z:3}, {x:2, y:1, z:8}, {x:2, y:6, z:5}, {x:2, y:9, z:8}];
    grps = data6.groupBy(a=>[a.x, a.z]);
  
  grps's value:
  [
    {
       key: [1, 3],
       list: [{x:1,y:6,z:3}, {x:1, y:5, z:3}]
    },
    {
       key: [2, 8],
       list: [{x:2, y:1, z:8}, {x:2, y:9, z:8}]
    },
    {
       key: [2, 5],
       list: [{x:2, y:6, z:5}]
    }
  ]
