`null` is one of the [[Primitive types]] in JS, used for denoting an *intentionally empty* value. It's one of the [falsy](https://developer.mozilla.org/en-US/docs/Glossary/Falsy) values.

JS [data types](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Data_structures#javascript_types) consist of primitives and objects. Objects contain properties, which contain key-value pairs. When we hear "objects",  we may imagine something like this:

```js
const user = {
  id: 123,
  username: "ekafyi",
}
```

But what type is `null`?

```js
console.log(typeof null) // ?? what r u?
```

As far as `typeof` is concerned, `null` is considered... an object.

Outside of this one case, `null` is still a primitive value and does not inherit the Object prototype (= does not behave like an object); you cannot, for instance, assign a property to `null`.

Fun times.
