如何按数字键值对对象进行排序

Question

I have an object that looks like this:

a = {10: 961, 11: 1418, 12: 1526, 13: 1652, 14: 1482, 15: 1581, 16: 1594, 17: 1201, 18: 816, 19: 994, 20: 455, 21: 910, 22: 1181, 23: 713, 00: 296, 01: 144, 02: 100, 03: 56, 04: 22}

How can I rearrange the order of the entries so it looks like

b = {00: 296, 01: 144, 02: 100, 03: 56, 04: 22, ...}

Not sure if this is relevant but I derive this object from a larger JSON object and need to sort it in order to display the data on a chart.

Answer 1

Properties to objects are ordered by integer values first and then by the string keys in order of their addition to the object. Therefore it IS possible to order the properties by creating a new object from your object.

a = {10: 961, 11: 1418, 12: 1526, 13: 1652, 14: 1482, 15: 1581, 16: 1594, 17: 1201, 18: 816, 19: 994, 20: 455, 21: 910, 22: 1181, 23: 713, 00: 296, 01: 144, 02: 100, 03: 56, 04: 22};

b = {};
Object.keys(a).sort((a,b) => { return parseInt(a) - parseInt(b);}).forEach((x) => {
b[x] = a[x];});
console.log(b)
