Sort objects in object by date React

Question

How I can sort my object after add one value

{
2017-12-18:{210: {…}},
2017-12-20:{211: {…}},
2017-12-21:{186: {…}, 188: {…}, 189: {…}, 190: {…}, 201: {…}}
}

And now I add object 2017-12-19:{220: {…}}, but how I can add this after date 2017-12-18 ?

I don't think order matters inside a JSON. Why do you need them sorted? — Jagdeep Singh, Dec 18 '17 at 13:17
I add something in React and I have to show this in view but msut be after date 2017-12-18 — Paweł Baca, Dec 18 '17 at 13:18
Maybe you want to make a sorted array from your object? `[{ date: '2017...' , payload: {210:...}}, ...]` — dhilt, Dec 18 '17 at 13:20
Insert the keys in any order and then do: `Object.keys(json).map(function(d){ return new Date(d) }).sort()`. This will give you the keys (as Date object) but sorted. I hope you can make some progress with this. — Jagdeep Singh, Dec 18 '17 at 13:22

Take a look at this answer for sort object by property name

You can just run that function after adding a new "line" to your object.

I would advise you to make sure you are not overwriting and existing property in your object before you attempt to add a new one.

This work

let sortedData = function sortObjectKeys(obj){
    return Object.keys(obj).sort().reduce((acc,key)=>{
        acc[key]=obj[key];
        return acc;
    },{});
}
