Summary

In this chapter, we have seen how to target JavaScript with haXe in order to manipulate the DOM.

Specifically, we covered:

  • How the haXe API lets us manipulate the DOM

  • What kind of caveats to avoid

  • How we can handle events with haXe

Now, for our last chapter, we are going to write a game in Flash!
