In this talk, we’ll explore “signals,” a powerful pattern for state management and UI updates that’s reshaping modern front-end frameworks. We’ll dive into how signals enable fine-grained reactivity, discuss their historical context, and see how they’re changing major frameworks like Angular and others. You’ll also get a look under the hood—how to build a simple signals implementation, plus a peek at how Angular is using this approach. Whether you’re an experienced JavaScript developer or just curious about the next evolution in reactive programming.
