Reactive programming ​

Super Charging Fine-Grained Reactive Performance & Hands-on Introduction to Fine-Grained Reactivity are great reads.

Love Solid's reactivity model. Voby & Signia interesting too.

Rust Signals library is interesting.

Notes ​

• Event streams (like plain observables) emits values. Signals (and behavior subjects) have values. Queues (channels and some buffered and published observables) hold/store values. For example seminal paper on functional reactive programming defines two primitives- event streams and behaviors. They have different laws and this different capabilities. Queues are even more powerful but provide less guarantees.
• Signals are not just about 'optimizing performance'. They do for ordinary data what React only does for DOM trees: provide a composable, consistent, managed way to derive it from your root application state, and to respond to changes over time.
