Javascript: How to Sort a regular object based on key and value

Assume like you have an object { '1': 1, '3': 1, '4': 3, '5': 1 } and you would like to sort it by its value.

Then you can follow below way. I just added debug information to help with visulization but the function you need is simply

Sort by value

Object.entries(obj).sort(function(a, b) { return a[1] - b[1] }); 

And if you would like to sort by key then

Object.entries(obj).sort(function(a, b) { return a[0] - b[0] }); 

Debug Code

> Object.entries(obj)                                                                                                                                                                                       
[ [ '1', 1 ], [ '3', 1 ], [ '4', 3 ], [ '5', 1 ] ]
