Sort Json Object in an array/text

I was wondering if i can sort the json keys in order as an array by the values.

Below is a json object
{ "p1": { "name": "*****", "age": "18" }, "p2": { "name": "*****", "age": "14" }, "p3": { "name": "*****", "age": "24" } }
and i want it to get sorted in array/text in ascending order by the values of the subkey "age".
["p2", "p1", "p3"]

I haven’t tried anything as I have no idea what to do, can someone return me an example…

>Solution :

You can simply use Object.keys and sort it based on their age properties:

const data = { "p1": { "name": "*****", "age": "18" }, "p2": { "name": "*****", "age": "14" }, "p3": { "name": "*****", "age": "24" }}

const dataKeysSortedByAge = Object.keys(data).sort((a, b) => data[a].age - data[b].age)
console.log(dataKeysSortedByAge)

If the snippet is confusing:

1. Object.keys returns an array containing the keys in the object
2. The sort function takes a callback containing two parameters, where a positive value means a is greater, and a negative value means b is greater
3. We subtract one property’s age from the other one; we can be lazy here and not convert the values to a number because substraction coerces the values to numbers
