Parser from the Jint version 2.X correctly processed this code. ChakraCore and V8 can also parse this code correctly.

How did I understand that current version of the Jint engine is not yet compatible with latest version of the Esprima parser?

In most cases, the following error occurs:

System.MissingFieldException: Field not found: 'Esprima.Ast.Program.Body'.
   at Jint.Engine.Execute(Program program)

Sounds odd, I think the current NuGet Jint references the latest published Esprima package and they are working together.

Nothing strange, just I locally builded a package with latest version of the Esprima parser.

@sebastienros should we release a new version of esprima and link Jint against it?

In principle, you can not rush, because I plan tomorrow to describe the error that occurs in the CoffeeScript.
