Is there support/extensions for evaluating TypeScript expression on a browser's console?

Question

The title says it: are there browsers in which I can directly evaluate TypeScript (rather than JavaScript) expressions directly in the console?

If not: do current browsers have APIs that could be used to develop plugins or extensions to do just that — integrating smoothly with the built-in console?

Not the built in console. But you can create a new TypeScript console. This would be similar to the coffescript console : https://developers.google.com/chrome-developer-tools/docs/sample-extensions#coffeescript_console

Should be simple enough to twist that to a TypeScript console if you want to. Its basically this line : https://github.com/snookca/CoffeeConsole/blob/master/src/coffee-console.html#L89 that needs to point to something like TypeString : https://www.npmjs.org/package/typestring. Syntax highlighting is a much more involved problem.
