    "07": 0,
    "08": 27.6,
    "09": 24.3
};

Sort by key value.

Answer 1

JSON is unordered, and the browser will automatically sort according to key, so sorting is useless.

Answer 2

It is recommended to convert to array first, then sort, and then convert to object

Answer 3

    var obj = {
      '10': 20.1,
      '11': 16,
      '12': 12.7,
      '01': 0,
      '02': 0,
      '03': 0,
      '04': 0,
      '05': 0,
      '06': 0,
      '07': 0,
      '08': 27.6,
      '09': 24.3
    }
    console.log(Object.keys(obj).sort().reduce((a, b) => (a[b] = obj[b], a), {}))

Answer 4

var arr = []
for (const key in obj) {
  arr[key] = obj[key]
}

This can achieve your needs

If the middle is not continuous, you need to filter it again later

Answer 5

Why do objects need to be sorted? Can’t we get the setting value directly through the key value?
