What is @section scripts and what it is used for

Question

A section allows you to add something in a view which will be added in the layout. ie:-

view

@section scripts {

    <script>

      alert('foo');

    </script>

}

layout

@RenderSection("scripts", false)

now this named section scripts will be rendered where you have specified in the layout.

@RenderSection also has 2 signatures:-

public HelperResult RenderSection(string name) // section required in the view
public HelperResult RenderSection(string name, bool required)
