Running Jurassic JavaScript from C# with a hint of dynamic

Jun 30, 2011 at 5:23 AM

I created a C# library that let you access the JavaScript objects and arrays in the C# world using the dynamic syntax available in JavaScript.
So you can write, the following C# code.

dynamic jsContext = new DynamicJavascriptContext(
jsContext.message = "Hello World !";
jsContext.number = 1;
string script = @"
    var i = 0;
    for (i = 0; i < 5; i++)
        console.log(message + ' (' + i + ')');
    number += i;
Console.WriteLine("number: " + jsContext.number);

See my post, and let me know your remarks.

Very cool!  I'd be interested in knowing what you are using this for - are you using it within another app you are building?  Or is this just a tech demo type of thing?

Paul, I am a .NET developer, which is also into dynamic languages. In the past I used IronPython to extend applications, see

But since late 2010, I am 100% in JavaScript, to build stuff from the server to my iphone. I want to be able to run JavaScript and maybe CoffeeScript from C#. 

Here is one first blog about it :

Another example:  A CoffeeScript compiler and run time

I do not have specific app where I am going to mix C# and JavaScript, but it is just a matter of time.

I wanted a more JavaScript like syntax in C#, that is why i wrote this library.

By the way Jurassic is awesome.

Thanks for the kind words :-)  I wish I had more time to spend on Jurassic (it'd be cool to implement runtime time analysis, for example), but unfortunately my day job is a demanding mistress.
