What is Signal Store, and what is it used for?

Signal Store is a pattern or data structure used in frontend development for managing application state with reactive signals. Unlike traditional stores, which are often based on immutable objects and reducers (e.g., Redux), Signal Store uses signals—objects that automatically track dependencies and update related components when the value changes.

The main purpose of Signal Store is to simplify state management, make it more reactive and efficient, and minimize re-renders and code complexity. This approach is often found in modern frameworks and libraries that support reactivity at the signal level.

Example usage (pseudocode):

const count = signal(0); // create a signal

function increment() {
  count.value += 1; // update the signal
}

// component will automatically update when count changes
render(() => {
  console.log(`Count is ${count.value}`);
});
