Kinda: https://svelte.dev/blog/runes https://svelte.dev/blog/runes > Svelte 5's reactivity is powered by signals, which are essentially what Knockout was doing in 2010. More recently, signals have been popularised by Solid and adopted by a multitude of other frameworks. > We're doing things a bit differently though. In Svelte 5, signals are an under-the-hood implementation detail rather than something you interact with directly.
