Compare objects in React Native

Question

How can I check if two JavaScript values are the same?

If they are objects, I would like to compare them key-by-key recursively.

I'm looking for an existing function, not a way to write my own like described in this question: Object comparison in JavaScript.

There's a function called deepDiffer which does this.

Took a bit of Googling to find how to import deepDiffer.

import deepDiffer from 'react-native/lib/deepDiffer'

...

deepDiffer(obj1, obj2) // true or false

In react native >= 0.62.2 use,

import deepDiffer from `react-native/libraries/utilities/differ/deepDiffer`

deepDiffer(obj1, obj2) // true or false
