Can JavaScript Engines Be Embedded in .NET?

Embed JavaScript engine in .NET

Question: Is it possible to embed and integrate a JavaScript engine into .NET?

Answer:

Yes, it is possible to embed and integrate JavaScript engines into .NET. One option worth looking at is the JavaScript .NET project hosted on GitHub. This project implements Google V8 to compile and execute JavaScript directly from .NET code.

JavaScript .NET provides two main features:

1. Compilation and Execution: JavaScript code can be compiled and executed directly from .NET assemblies.
2. Interacting with CLI objects: JavaScript is able to interact with objects exposed in the Common Language Infrastructure (CLI), allowing seamless method calls between JavaScript and C# objects.

Example:

// C#类
public class A
{
    public string Hello(string msg)
    {
        return msg + " whatever";
    }
}

// JavaScript代码片段
var a = new A();
console.log(a.Hello('Call me'));

In this example, the JavaScript "a" object can call the "Hello" method of the C# "A" class.

Other JavaScript engines:

While JavaScript .NET implements V8, there are other engines available for integration into .NET. These include:

• SquirrelFish
• SpiderMonkey

However, the experience of using these engines may vary, especially in terms of maturity and continued development.
