+Svelte sports a reactive system that allied with a pre-compiler makes binding program variables to HTML elements pleasingly easy and concise. However there were some annoying edge cases that caused problems. Svelte 5 (aka Runes) fixes these using the Signals pattern. We’ll demonstrate these issues and how runes rides to the rescue. Finally we’ll cover the uptake of signals in the wider JavaScript ecosystem, including the latest TC39 standardisation.
