What makes WebAssembly fast?
It's both amusing and absurd that what was practically intended as Java's little helper, JavaScript, has grown up to be this thing that might actually replace Java entirely.<p>How long until there's a really good JVM written in JavaScript of some form and embedded Java apps end up running in JavaScript for performance <i>and</i> security reasons?<p>It'll be even more ridiculous and hilarious if the "j" in "jruby" ends up meaning "JavaScript".
