How to get the difference between two arrays of objects in JavaScript

Question

I have two result sets like this:

// Result 1
[
    { value: \"0\", display: \"Jamsheer\" },
    { value: \"1\", display: \"Muhammed\" },
    { value: \"2\",         


        

Answer 1

import differenceBy from 'lodash/differenceBy'

const myDifferences = differenceBy(Result1, Result2, 'value')

This will return the difference between two arrays of objects, using the key value to compare them. Note two things with the same value will not be returned, as the other keys are ignored.

This is a part of lodash.
