How to sort array of object to descending order in Angular

Question

Array of objects

this.sampleArray = [{ID: 176, active: true },
 {ID: 181, active: false },
 {ID: 186, active: true }];

How to use Angular TypeScript to order them in descending order.

I am using the following:

const result= _.sortBy(_.where(this.sampleArray, 'ID')).reverse();

But this is not reliable as the ID order keep on changing from descending to ascending. I am using underscore library

It looks like you're using a library like lodash or underscore. Please [edit] your question and add the tag if you expect answers to use that library. — Heretic Monkey, Apr 16 '20 at 18:35

YOu can use the simple sort method provided by the javascript.

this.sampleArray = [{ID: 176, active: true },
 {ID: 181, active: false },
 {ID: 186, active: true }];

this.sampleArray.sort((a, b) => b.ID - a.ID);

Working code:

const arr = [{ID: 176, active: true },
 {ID: 181, active: false },
 {ID: 186, active: true },
 {ID: 183, active: true }];
 
 arr.sort((a, b) => b.ID - a.ID);
 
 console.log(arr)
