Use a custom sort function and add some hard constraints. Could have some minor issues, but shoud be ok for the most part

 let obj = [{ type: 'Premium', date: new Date('1995-12-17T03:24:00') }, { type: 'random', date: new Date('1995-12-17T03:24:00') }, { type: 'Premium', date: new Date('1995-12-17T03:22:00') }, { type: 'random', date: new Date('1995-12-17T03:21:00') }, { type: 'random', date: new Date('1995-12-17T03:20:00') }] let obj2 = obj.sort((x, y) => { if(x.type == 'Premium') return 1 if(y.type == 'Premium') return -1 if(x.date > y.date) return 1 if(x.date < y.date) return -1 return 0 }).reverse() console.log(obj2)
