How to use TypeScript on a button click

I need to call a function on certain event.

If the function is global e.g. TypeScript:

function foo(){
   alert('foo');
}

Just use onclick e.g. html:

<button onclick="foo()">click me!</button>

Remember TypeScript is (almost) JavaScript.

However I recommend using a framework like angular with TypeScript. For maintainability. As an example take a look at the browser quickstart.
