Answer 1

you could also use lodash.get

You just install this package (npm i --save lodash.get) and then use it like this:

const get = require('lodash.get');

const myObj = { user: { firstName: 'Stacky', lastName: 'Overflowy' }, id: 123 };

console.log(get(myObj, 'user.firstName')); // prints Stacky
console.log(get(myObj, 'id')); //prints  123

//You can also update values
get(myObj, 'user').firstName = John;
