The FlexJS framework is designed to work well with ActionScript and JavaScript. The philosophy is that if it works in ActionScript, it should work in JavaScript, too, and vice-versa. You create a component (or bead) in one language and then port that functionality to the other language. Note that you port the functionality and not the code.

You want to make things as efficient as possible in both environments. For instance, the TextInput component in ActionScript is comprised of view and model beads. The JavaScript TextInput has neither since HTML has a view and model already (the DOM), the FlexJS TextInput component is just a thin wrapper for the HTML control. When you begin creating your JavaScript component, take the time to understand the best way to represent it so the component is as optimal as possible.

As components become more complex, such as with the Slider component, more of the ActionScript style is present in JavaScript.
