How to compare two objects and return the discrepancies in a new typescript object?

Question

JavaScript

I need to check for the identity of the key and value of these two objects, if the data does not match, return them to a separate object,
I need it to check only for these fields

"name": "Jeans",
"picture": "https://www.google.com",
"description": "text",
"quantity": 123,
"price": 123,
"sale": 123,
"afterSale": 4000,
