# Strings as object keys in JavaScript

Strings can be object keys:

`let obj = {'a': 1, 'b': 2, 'c': 3};`

In this case, it is common practice not to put the string keys in quotes:

`let obj = {a: 1, b: 2, c: 3};`

Let's retrieve the element of our object by key:

`console.log(obj['a']); // shows 1`

Create the object `user` with the keys `'name'`, `'surname'`, `'patronymic'` and some arbitrary values. Display the last name, first name and patronymic separated by a space.
