I'm wondering how to make use of an existing object system. We already have a JS framework that simulates classes and inheritance in the Java-style OOP.
If you have a small sample, you could try it out in the playground (http://www.typescriptlang.org/Playground/) and see what TypeScript can recognize. Generally, I've seen TypeScript plays well with other OO forms and gives you intellisense on quite a lot.
