Managing reactive state and dependent computations in JavaScript can get complex, especially when combining asynchronous and synchronous data. RS-X is a library that allows you to bind expressions to plain objects and makes the parts of the model used by those expressions fully reactive. Dependent computations automatically update when the underlying data changes.

RS-X is framework-agnostic. While it can drive UI updates (Angular integration is available, React integration planned), it works equally well for server-side logic, business rules, or any reactive workflow. Expressions are parsed and managed with a reactive engine, and developers can subscribe to `changed` events when needed.
