The Power of WebAssembly

WebAssembly, this stuff gets super interesting. I saw there's a project which does the entire Python data stack. Google Chrome DevTools developer evangelism team put out squoosh.app - an image compression website. So now your browser has the best in class implementations of compression for, like, three or four different formats. You literally drag an image onto this onto this page. It shows you a preview of before and after with a little slide, slide back and forth.
