                ["aa009":
                {
                "id":"aa009"
                "aa009":"86"
                }
            ],
        }
    ]

I want to output the above JSON data in groups according to GROUP to the following format. How to operate it with JS? thank you.

function handle(list) { const obj = {}; list.forEach(item => { let { group, name, value } = item; let temp = { id: name, [name]: value, }; if (obj[group]) { obj[group].push(temp); } else { obj[group] = [temp]; } }); return Object.values(obj).map(val => { return { [val[0].id]: val, }; }); }
