Question

I am trying to create to javascript/jquery test to check if my object is empty and cannot figure it out.

Here is the object when it has something in it:

Answer 1

If you are using lodash library, you have an elegant way to check an empty object, array, map or a set. I presume you are aware of ES6 Import statement.

import {isEmpty} from "lodash"

let obj = {};
console.log(isEmpty(obj)); //Outputs true.

let arr = [];
console.log(isEmpty(arr)); //Outputs true.

obj.name="javascript";
console.log(isEmpty(obj)); //Outputs false.

So, for your code,

isEmpty(mergedSellerArray); //will return true if object is not empty.

Hope this answer helped.
