The argument that React will be heavier than your own implementation is clearly true.<p>The argument that it&#x27;ll take less time to develop, document, and test your own implementation than to take advantage of the React ecosystem is clearly untrue.<p>As the public demands higher quality images and video, code weight matters less and less. If you&#x27;re not serving up 3mb+ of high-res images and&#x2F;or video and making multiple AJAX calls, your site is highly specialized and outside of the mainstream. It&#x27;s not an insult or a judgement, it&#x27;s an easily verifiable fact by looking at Alexa ratings.<p>If you need to save 50-100kb that badly, use a slightly smaller image file or a slightly shorter video, don&#x27;t add hundreds to thousands of hours of dev time. And if you&#x27;re developing for mobile, do as much server-side rendering as you can and add a debounce for potentially costly operations, it&#x27;s really not that hard.
