jQuery DomHepler

Hello. I trying to find jQuery DomHepler plugin on native method whitch helps me create simple dom constructions
like this in ExtJs
  1. myDiv = Ext.DomHelper({
  2.       tag : 'div',
  3.       cls : ''myDivClass'
  4.       children : [{
  5.                   tag : "span"
  6.                    },{
  7.                   tag : "span"
  8.                   }]
  9.       })
this returns me a div with 2 childs.
is it exist?
Thanks.
