how one would go about using Triangulator in javascript?

I'm aspring to learn procedural mesh creation. Thought that using triangulator would be a good start. It's written in C# though and I'm not sure on how to convert

Triangulator tr = new Triangulator(vertices2D);

to javaascript or even if javascript would cross-work with this C# script. would it? any pointers on where to start about procedural mesh generation? I travel around the unityanswers, it gives me some great tips, also I know about procedural unity exapmle project, though there are scripts written in C# too, which is kind of off-putting. Unless, there isn't that much difference one from the other and it could be learned how to understand C# code java way.

Thanks in advance.
