&gt; Large React apps are actually no faster than large apps written in Ember or Angular<p>This is (more or less) true now. It wasn&#x27;t when React first showed up. Angular is also only just as fast when you actively code your apps in the same way as React (basically using a prop&#x2F;state system but in an Angular way). This isn&#x27;t also the method generally championed in Angular (1.x anyhow).<p>Ember was always pretty fast but post-React it changed a lot of how it did it&#x27;s rendering... influenced by React!<p>So claiming that React apps are no faster is a bit disingenuous as the reason for that is because the other frameworks saw what React was doing <i>and agreed with it</i>.
