Electron, Web Components, etc...<p>&gt; &quot;Do you even have evidence that it&#x27;ll be better than what we have now in other languages if it does take over?&quot;<p>Compare the performance of vanilla JS vs. asm.js. It is clear from what developers have stated that WebAssembly performance will exceed the performance of asm.js, the threading improvements alone should offer noticeable benefits.<p>&gt; &quot;Years of experience making them more accessible, more usable, more consistent with the platform they&#x27;re running on, etc.&quot;<p>So what are we looking at to replicate that? A theme per platform? Some accessibility work? What else?<p>It should be noted that the web isn&#x27;t starting from zero with UX either, we&#x27;ve already had 20+ years of refinements to the web user experience.
