i would like to assign one more value on the array. It should be loop thought to assign it?

var datelist = [{ "date": 01/07/2022, "time": "11:00", },{ "date": 11/07/2022, "time": "18:00", },{ "date": 31/07/2022, "time": "19:00", }]

Now , I would like to change as this format , which is merged the this 2 field and add "(" and ")"

var datelist = [ {
"date": 01/07/2022,
"time": "11:00",
"applyDateTime": "01/07/2022 (11:00)"},{
"date": 11/07/2022,
"time": "18:00",
"applyDateTime": "11/07/2022 (18:00)"},{
"date": 31/07/2022,
"time": "19:00",
"applyDateTime": "31/07/2022 (19:00)"}]
