javascript - How to sort only few elements in an array of object by date property

Question

I have an array of objects like below.

var array = [{id: 1, date:'Mar 12 2012 10:00:00 AM', status:'done'}, 
                 {id: 2, date:'Mar 8 2012 08:00:00 AM', status:'done'},
                 {id: 3, date:'Mar 15 2012 10:00:00 AM', status:'done'}, 
                 {id: 4, date:'Mar 5 2012 08:00:00 AM', status:'done'},
                 {id: 5, date:'Mar 30 2012 10:00:00 AM', status:'done'}, 
                 {id: 6, date:'Mar 5 2012 08:00:00 AM', status:'done'},
                 {id: 7, date:'Mar 1 2012 10:00:00 AM', status:'done'}, 
                 {id: 8, date:'Mar 7 2012 08:00:00 AM', status:'notdone'},
                 {id: 9, date:'Mar 12 2012 10:00:00 AM', status:'notdone'}, 
                 {id: 10, date:'Mar 2 2012 10:00:00 AM', status:'notdone'}, 
                 {id: 11, date:'Mar 6 2012 10:00:00 AM', status:'notexist'}, 
                 {id: 12, date:'Mar 8 2012 08:00:00 AM', status:'notexist'}];

I am trying to sort first few elements in my array which has status:'done' and leave remaining records as it is.

Can someone help me with how I can put this condition and sort the elements.

Thanks.

var array = [{id: 1, date:'Mar 12 2012 10:00:00 AM', status:'done'}, 
                 {id: 2, date:'Mar 8 2012 08:00:00 AM', status:'done'},
                 {id: 3, date:'Mar 15 2012 10:00:00 AM', status:'done'}, 
                 {id: 4, date:'Mar 5 2012 08:00:00 AM', status:'done'},
                 {id: 5, date:'Mar 30 2012 10:00:00 AM', status:'done'}, 
                 {id: 6, date:'Mar 5 2012 08:00:00 AM', status:'done'},
                 {id: 7, date:'Mar 1 2012 10:00:00 AM', status:'done'}, 
                 {id: 8, date:'Mar 7 2012 08:00:00 AM', status:'notdone'},
                 {id: 9, date:'Mar 12 2012 10:00:00 AM', status:'notdone'}, 
                 {id: 10, date:'Mar 2 2012 10:00:00 AM', status:'notdone'}, 
                 {id: 11, date:'Mar 6 2012 10:00:00 AM', status:'notexist'}, 
                 {id: 12, date:'Mar 8 2012 08:00:00 AM', status:'notexist'}];
                 
var doneItems = array.filter(r => r.status === 'done');
var remainingItems = array.filter(r => r.status !== 'done');

doneItems.sort((a, b) => (new Date(a.date) - new Date(b.date)));

console.log(doneItems.concat(remainingItems));
