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.

Future improvements in Rust and WebAssembly may allow for more efficient interactions with browser APIs, but significant challenges remain in achieving this.

The cost of running a WebAssembly app is primarily the cost of downloading it, and even a minimal WebAssembly application can be quite small, often in the dozens of kilobytes.

Canvas runs in a sandbox environment, allowing me to make secure API calls with network controls.

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 frameworks require a large amount of code to be shipped, which can cost companies millions in loading time, making them less appealing for e-commerce applications.

The integration of WebContainer technology allows Bolt to create a dramatically faster and more reliable AI coding experience than competitors.

The foundational crates for building Rust web applications include WM Bindgen and WebSys, which facilitate interaction with JavaScript and browser APIs.

Years of hard work and development led to the creation of WebContainer technology, which enables Bolt to run a browser-based operating system, making it faster and more reliable than competitors.
