SignalDB is a client-side database that provides a simple MongoDB-like interface to the data with first-class typescript support to achieve an optimistic UI. Data persistence can be achieved by using storage providers that store the data through a JSON in

//#region src/utils/createSignal.ts
/**
* Creates a reactive signal for managing state and triggering dependencies.
* The signal holds a value and provides methods to get and set the value,
* with optional equality checks and dependency tracking.
* @template T - The type of the value held by the signal.
* @param reactivityAdapter - An optional reactivity adapter for managing dependencies.
* @param initialValue - The initial value of the signal.
* @param isEqual - A custom equality function to determine if the new value is different
*   from the current value (default is `Object.is`).
* @returns A signal object with `get` and `set` methods to manage the value.
