Location: Runway East Brighton

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.

Pizzas provided by our venue! Runway East has been fighting boring offices since 2014. Members get team bliss guaranteed with space to scale. [Learn more.](https://runwayea.st/locations/brighton?utm_source=external&utm_medium=event&utm_campaign=sponsorship)

🍻 **BYOB:** We are currently looking for additional sponsorship. This event will likely not have a sponsor for drinks, so if you'd like to have a couple during the event please bring some of your own (and maybe some to share if you're feeling generous).

**In-person attendees**: Please arrive at Runway East (ground floor) between 19:00 and 19:15 for refreshments and socializing. Make sure you are registered to attend so we have an idea of numbers for catering.

**Remote attendees**: We will start broadcasting the event at 19:30 online [via YouTube](https://www.youtube.com/watch?v=wypos_DZdyo), there is no need to register.
