Why we should use xaml in Wpf ?

The specific advantage that XAML brings to WPF is that XAML is a completely declarative language, allowing the developer (or designer) to describe the behavior and integration of components without the use of procedural programming. Although it is rare that an entire application will be built completely in XAML, the introduction of XAML allows application designers to more effectively contribute to the application development cycle. Using XAML to develop user interfaces also allows for separation of model and view, which is considered a good architectural principle. 

"XAML is used when we have two systems which are in heterogeneous in nature.so WPF internal representation is XAML.so if we create the UI in XAML than it can be render on windows application,web application inside browser."
