javascript之使用 sort() 移动数组开头的对象

const array = [ 
  { date: 624000, name: 'Eddison', }, 
  { date: 224000, name: 'Bobby', }, 
  {               name: '--no date 2' }, 
  { date: 924000, name: 'Fred', }, 
  { date: 124000, name: 'Abe', }, 
  {               name: '--no date 1' }, 
  { date: 424000, name: 'David', }, 
  { date: 324000, name: 'Catheryn', }, 
]; 
 
// assuming there is no 0 date 
array.sort(function(a, b) { 
  return (a.date && b.date) 
      ? new Date(b.date) - new Date(a.date) 
      : (a.date || 1) - (b.date || 1);  
}); 
 
//result 
array.forEach(elem => console.log(JSON.stringify(elem)));
