So for a little context, my object is

const obj: {[key: string]: any} = {
        "1000": {
            "time": "2022-05-14T10:00:00:000Z",
            "availableSlots": 0,
            "availability": false
        },
        "1400": {
            "time": "2022-05-14T14:00:00:000Z",
            "availableSlots": 4,
            "availability": true
        },
        "0800": {
            "time": "2022-05-14T08:00:00:000Z",
            "availableSlots": 3,
            "availability": true
        },
        "0830": {
            "time": "2022-05-14T08:30:00:000Z",
            "availableSlots": 2,
            "availability": true
        }
    }

and I want my object sorted by the key. When I sort my Object entries, I'm able to sort them by keys by using

const x = Object.entries(obj).sort((a,b): number => {
    if (parseInt(a[0]) > parseInt(b[0])) { 
        return 1 
    } return -1
})

But when I try to reduce it to make it into an object again, it's not sorted again

const x = Object.entries(obj).sort((a,b): number => {
    if (parseInt(a[0]) > parseInt(b[0])) { 
        return 1 
    } return -1
}).reduce((prev, [hour, hourInfo]) => ({ ...prev, [hour]: hourInfo }), {})

Online Compiler of the problem: link

I'll compare times with the time field using dayjs but for the online compiler I used the keys for an easier comparison
