JavaScript - get sorted object properties by value

In this article, we would like to show you how to sort object properties by value in JavaScript.

Practical example:

// ONLINE-RUNNER:browser;

let object = {'b': 2, 'c': 3, 'a': 1};

let sorted = Object.entries(object)
                   .sort((a, b) => a[1] - b[1]);

console.log(sorted);  // a,1,b,2,c,3

The above example shows how to sort obj object properties by value using Object.entries() method which returns the object's [key/value] pairs in the same order as a for...in loop.
Then we sort entries array with .sort() method passing arrow function that compares values. 

Note:

Above solution is safe because, it behaves like for ... in loop with checking condition if an object has a specific own property (like Object.prototype.hasOwnProperty()).
