Javascript自定义排序——node运行

var studs = [{name: 'clap', age: 15},              {name: 'martin', age: 13},             {name: 'merry', age: 10}];function sortbyage(a, b){//按年龄从小到大排列  return a.age > b.age;}function sortbyname(a, b){  return a.name > b.name;}//按年龄排序studs.sort(sortbyage);for(var i = 0; i < studs.length; i++)  console.log(studs[i]);  //按姓名排序studs.sort(sortbyname);for(var i = 0; i < studs.length; i++)  console.log(studs[i]);
