Our Commentary ​

The ShadowRealm API is something we've been eagerly anticipating! True JavaScript isolation has been a long-standing challenge, especially for complex applications and component libraries that need to load untrusted code or manage dependencies without interference. The idea of "banishing JavaScript to the ShadowRealm" sounds dramatic, but it's exactly what we need for more resilient and secure web development. This could be a game-changer for frameworks and micro-frontends.
