js将一位数组分割成每三个一组

var data = [ 
  {name:'Liming',age:'25'},
  {name:'Liming',age:'25'}, 
  {name:'Liming',age:'25'}, 
  {name:'Liming',age:'25'}, 
  {name:'Liming',age:'25'}, 
  {name:'Liming',age:'25'}, 
  {name:'Liming',age:'25'}, 
  {name:'Liming',age:'25'}, 
  {name:'Liming',age:'25'}, 
  {name:'Liming',age:'25'}, 
]
var result = [];
for(var i=0;i<data.length;i+=3){
    result.push(data.slice(i,i+3));
}
