This appendix will provide a brief reference of the syntactical differences between C# and JavaScript in Unity. This section references from the Unity answer forum:
http://answers.unity3d.com/questions/12911/what-are-the-syntax-differences-in-c-and-javascrip.html.
Unity has a number of Script Directives, and we can find them at this URL: http://unity3d.com/support/documentation/ScriptReference/20_class_hierarchy.Attributes.html, for example RequireComponent.
JavaScript:
@script RequireComponent(Rigidbody)
C#:
[RequireComponent(typeof(Rigidbody))]
