js将一组数组分割成每三个一组

var data = [
  {name:'z',age:'1'},
  {name:'x',age:'2'},
  {name:'c',age:'3'},
  {name:'v',age:'4'},
  {name:'b',age:'5'},
  {name:'n',age:'6'},
  {name:'m',age:'7'},
  {name:'a',age:'8'},
  {name:'s',age:'9'},
]
var result = [];
for(var i=0;i<data.length;i+=3){
    result.push(data.slice(i,i+3));
}
