# 5.18 What's next And that concludes our overview of how a program operates within the Deno environment. We've journeyed from the starting point to the finish line, covering the essential steps along the way. This initial example marked our first foray into Deno, and while it may have been straightforward, its simplicity proved incredibly valuable in grasping the fundamental concepts. By sidestepping the intricacies of more complex user programs, we were able to focus on building a solid foundation of understanding. Now that we've grasped the fundamentals, we're ready to move forward. Next, we'll explore a simple program that introduces an asynchronous event triggered by a timer. In the next chapter of this book, we'll examine a program that incorporates various imports and operations. This will further enhance our understanding of Deno's capabilities and demonstrate how to effectively leverage its features. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
