implementation browser application in typescript.
can anyone give a link?

Your posts show a possible fascination with TypeScript. TypeScript is a Microsoft idea about JavaScript so you would be looking for such in JavaScript then port it over.

Let me blow up your ideas about TypeScript. It's not going to get a lot of traction for many reasons in the open source community. I suggest if you want a browser from source you start with one of the many open source browsers and go from there.
