Well, JavaScript became popular, because it was omnipresent and was simple (so that even Web Designers without a Computer Science degree could use it). Now, there are vast differences between browsers and the toolchain has grown huge.<p>We need to revisit the scripting in browsers. Instead of twisting arms to use &quot;JavaScript&quot;, because of it &quot;universality&quot;, we should focus on WebAssembly and the likes. Have a safe scripting VM in the browser, use any language that compiles to it - no need for Babel and the likes.
