In this talk, Brian will dive into the emerging world of Functional Web Apps (FWA), redefining web development through the lens of functional programming concepts. He will explore how FWA leverages functional programming paradigms to create more efficient, reliable, and maintainable web applications.

The discussion begins with an overview of functional programming principles and their benefits in software development, focusing on immutability, pure functions, and higher-order functions. He'll contrast these with traditional imperative and object-oriented approaches, highlighting how functional programming can lead to fewer side effects and easier-to-understand code.

Next, he delves into the core concepts of FWA, emphasizing how these applications differ from traditional web apps. He'll explore the architecture of FWAs, including state management, data flow, and UI rendering, demonstrating how functional concepts are applied in these areas. This section includes practical examples and code snippets to illustrate these ideas in action.

Brian then addresses the challenges and solutions in adopting FWA in real-world contexts. This includes integrating with existing codebases, team adaptation, and the learning curve associated with functional programming.

The talk concludes with a look at the future of FWA, considering its potential impact on web development trends, tooling, and frameworks. He'll also discuss how FWAs can contribute to scalable, robust, and performant web applications, ultimately leading to a better user and developer experience.
