How Can I Sort JavaScript Objects by Their Property Values?

Sorting Objects by Property Values in JavaScript

In JavaScript, objects are collections of key-value pairs. While objects do not inherently have a specified order for their properties, there are methods to sort them based on property values.

Solution:

To sort an object's properties by their values, we can employ the following approach:

// Convert the object to an array
let sortable = [];
for (let key in object) {
    sortable.push([key, object[key]]);
}

// Sort the array based on values
sortable.sort((a, b) => a[1] - b[1]);

// Convert the sorted array back to an object
let sortedObject = {};
sortable.forEach((item) => (sortedObject[item[0]] = item[1]));

Example:

Given the following object:

let obj = {
  "key1": 100,
  "key2": 25,
  "key3": 50
};

Using the above solution, we can sort the object's properties by their values:

// Convert the object to an array
let sortable = [];
for (let key in obj) {
    sortable.push([key, obj[key]]);
}

// Sort the array based on values
sortable.sort((a, b) => a[1] - b[1]);

// Convert the sorted array back to an object
let sortedObject = {};
sortable.forEach((item) => (sortedObject[item[0]] = item[1]));

// Resulting sorted object
console.log(sortedObject);
//{ key2: 25, key3: 50, key1: 100 }

Caution:

While sorting object properties by values can be useful, it's important to note that JavaScript objects do not have a guaranteed order for their properties. This means that the order of the properties in the sorted object may not be reliable and may change in future versions of JavaScript.
