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)));

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'   } 
      ];

array.sort((a,b)=> (a.date)?         // if (a.date !== undefined) 
                   (b.date)?         // if (b.date !== undefined) 
                   (new Date(b.date) -new Date(a.date))
                   :+1              // for b.date is undefined
                   :-1 )            // for a.date is undefined

//result
for (x of array) console.log(JSON.stringify(x));
