# Dot Access and Method Calls

Dot notation accesses properties and methods on objects.

## Property Access

```ts
const user = { name: 'Mathias', age: 30 };
console.log(user.name); // 'Mathias'
```

## Method Call

```ts
const text = 'hello';
console.log(text.toUpperCase()); // 'HELLO'
```

In your code:

```ts
backendPeriodLabelFormatter.formatToParts(date)
```

- `backendPeriodLabelFormatter` is an object.
- `formatToParts` is a method.
- `(date)` passes the argument.

## Python Comparison

Equivalent idea to `obj.attr` and `obj.method(arg)`.
