How to get a value declared using const?

[Tacodiva]

Hi, I'm a newbie trying to use Jint and I've encountered a problem. I understand you get values like this:

Console.WriteLine(new Engine().Execute("var x = 10;").GetValue("x")); // 10

But when I try to use the GetValue method on a variable declared using const, it doesn't seem to work.

Console.WriteLine(new Engine().Execute("const x = 10;").GetValue("x")); // undefined

How do I get the value of x when it is a const?

GetValue resolves from object's properties, in this case from global environment's variable environment (which is basically the global object). You need to use Evaluate get access items seen by script, in this case the lexical environment which contains let/const/class.

Console.WriteLine(new Engine().Execute("const x = 10;").Evaluate("x")); // 10
