# Iterable : Set & List

* Both `List` and `Set` are `Iterable`, so they have the same methods and properties as the `Iterable` class.
    
* A `Map` uses a different data structure internally, depending on its implementation. For example, [HashMap](https://api.dart.dev/stable/dart-collection/HashMap-class.html) uses a hash table in which the elements (also called *values*) are obtained using a key.
    

# Example

```dart
Iterable<int> iterable = [1, 2, 3];
```

# Map:

* A Map uses a different data structure internally, depending on its implementation.
    
* For example, HashMap uses a hash table in which the elements (also called values) are obtained using a key.
