Performance is often cited as the &quot;big win&quot; that React brings to web development; I really wish that wasn&#x27;t the focus that (what seems like) most people take.<p>The DOM isn&#x27;t (that) slow; it&#x27;s all the crap we do to it that makes it slow.<p>React&#x27;s strongest selling point is its ergonomics: It frees the developer from having to write huge swaths of code that they otherwise would be with most previous libraries&#x2F;frameworks.<p>It achieves that with its immediate mode rendering: you no longer have to reason about how to transition the DOM from one state to another (in nearly all cases).
