js把一个数组分割成每三个一组

var data = [
  {name:'xue',age:'20'},
  {name:'bing',age:'21'},
  {name:'hu',age:'22'},
  {name:'wang',age:'23'},
  {name:'li',age:'24'},
  {name:'wan',age:'25'},
  {name:'kang',age:'25'},
  {name:'hua',age:'26'},
  {name:'kai',age:'27'},
  {name:'fang',age:'28'},
]
var result = [];
for(var i=0;i<data.length;i+=3){
    result.push(data.slice(i,i+3));
}
