Signals: Directed Data Graph with Synchronous Execution
Signals are not just like event emitters, but instead, they form a directed data graph where multiple signals are created to listen to other signals and trigger effects.

Accessing values under a scope creates a dependency, ensuring that any update triggers the signal's execution. Signals are gaining popularity due to their synchronous execution guarantees.
