Episode notes

The chapter traces the evolution of web development tools and technologies, from the early stages of building web ecosystems to the current era of serverless and container technologies like Lambda. It discusses the challenges and advancements in the e-commerce sector, emphasizing the focus on user experience to drive revenue growth. The chapter explores the development of LLRT, a specialized JavaScript runtime for serverless architecture, and its benefits in enabling event-driven applications and simplifying infrastructure management for developers.

Scott and Wes chat with Richard Davison from AWS about LLRT, a new runtime tailored specifically for Lambda. They dive into the benefits of using LLRT, challenges with JavaScript in serverless, and why Rust was chosen for its development.
