Flex or Ajax .. well both!

The release of Flash Player 9 included a new External API using a class file called the ExternalInterface that allows for the communication between JavaScript and Flash applications. To create the communication link and pass data between JavaScript and Flex, the developer had to create custom code to handle each call.

The newly introduced Flex-Ajax Bridge has simplified the usage of this API. By simply including the necessary classes, the bridge exposes all of the classes within the Flex application to JavaScript. You can almost create anything in your Flex application using JavaScript instead of ActionScript.

So if you are a JavaScript pro and want to try out Flex this is a good time to do so!
