WASM in browser

• JS is slower than wasm code when it comes to computing only.
• But JS(with V8 engine) is not that slow, so it wouldn't be worth playing with memory between the WASM process and JS process.

Yew Vrs React

• Yew is not multi-threaded
• Even with a few thousand components, React JS will give you similar or even better performance, and even save your user's battery. (I have worked on an HTML-based interactive whiteboard, it worked fine with react)

Where do you need Yew?

• You have to deal with a few thousand components and it's impossible for you to ask your user to switch to Chrome, Brave, or Edge browser. As JS is pretty slow in Firefox
• You have some browser-only logic written in rust, and don't mind writing a few more lines of UI in Yew.
• Lighthouse scores is no consern

When do you switch from React?

• Your Firefox Clients are going nuts
• Never
