Signal

A named reactive signal for the Datastar frontend framework.

Represents a client-side signal identified by name. Signal names are validated at construction time. Literal names are checked at compile time, and dynamic names are checked at runtime. Names must be dot-separated JavaScript identifiers and must not contain __, which Datastar reserves for modifier syntax. Use := to create a SignalUpdate that pairs this signal with a JSON-serialized value.

val count = Signal[Int]("count")
count := 0  // SignalUpdate ready for patchSignals
