 The `BottomNavigation` component provides a simple way to navigate between different views while providing common UI for both iOS and Android platforms.  The recommended scenario suitable for `BottomNavigation` is a high level navigation with 3 to 5 tabs each with separate function. For additional information and details about bottom navigation refer to [the Material Design guidelines](https://material.io/design/components/bottom-navigation.html#usage).
 
-> **Note:** NativeScript 6 introduced two new UI components called `BottomNavigation` and `Tabs`. The idea behind them is to provide more control when building tab based UI, while powering the CSS styling, the icon font support and other specific functionalities.

With `BottomNavigaiton` and `Tabs` coomponents available, the `TabView` can be considered obsolete.
