In this chapter, we covered the Core component of MooTools, which is split up into two sub-components: Core->Browser and Core->Core.
Specifically, we:
Learned how to obtain information about the client using browser properties, such as what browser they're using and what operating system they're using
Explored the Core->Core's useful (and not so useful) helper/utility functions
Now that we've learned about the Core component, we're ready to animate objects in the DOM, which is the topic of the next chapter.
