a utility to map objects props with handy config!
npm install paix

yarn add paix
Then...
import { paix } from 'paix';
const source_object = { FirstName: "Jhon", LastName: "Doe", Ignored: true };
const replacement = { FirstName: 'first_name', LastName: 'last_name' };
const modified_object = paix(source_object, replacement);
console.log(modified_object);
// { Ignored: true, first_name: 'Jhon', last_name: 'Doe' };
