 An object can be created with figure brackets `{…}` with an optional list of *properties*. A property is a "key: value" pair, where `key` is a string (also called a "property name"), and `value` can be anything.

 There's a standard algorithm for deep cloning that handles the case above and more complex cases, called the [Structured cloning algorithm](https://w3c.github.io/html/infrastructure.html#internal-structured-cloning-algorithm). In order not to reinvent the wheel, we can use a working implementation of it from the JavaScript library [lodash](https://lodash.com), the method is called [_.cloneDeep(obj)](https://lodash.com/docs#cloneDeep).
