WebAssembly and JavaScript have different costs in the browser; JavaScript is interpreted and must be fully downloaded and parsed, while WebAssembly is designed for streaming compilation, making it faster to load.

WebAssembly currently cannot directly call browser APIs due to its sandboxed nature, requiring data to be passed through JavaScript, which can introduce latency.

In server-side rendered applications, the time to interactive is proportional to the amount of content on the page, meaning more content can slow down loading and interactivity.

The current limitations of using Rust for web applications include compile times, binary sizes, and the ecosystem surrounding Rust web development.

Before writing a line of code for Next.js, I outlined seven principles of what the ideal state-of-the-art web would be, including instant loading and real-time data.

Using third-party frameworks and APIs can significantly speed up the MVP development process, allowing startups to avoid building everything from scratch.

Libraries and frameworks can be great dev tools, but they often face challenges in monetization; offering a hosting service can be a viable way to generate revenue from these tools.

Using Islands architecture, you can hydrate only the interactive parts of a page, which can significantly reduce the amount of WebAssembly shipped to the user's browser, leading to faster load times.

JavaScript is a beautiful language that allows beginners to express ideas with minimal effort, making it a great first language to learn.
