Our Commentary ​

This JavaScript Weekly issue is packed! The MDN news is a huge statement – ditching React for web components on such a foundational resource is a bold move that speaks volumes about the maturity and capabilities of native web technologies. It's a strong signal for the "less JavaScript" movement. Bun's continued rapid development, especially with native browser automation, is also incredibly exciting and positions it as a serious contender in the runtime space. And of course, a React security fix is always something to pay attention to. It feels like the web platform is truly coming into its own, offering compelling alternatives to traditional frameworks.
