EvaluateState

EvaluateState is a JavaScript library designed to help developers manage and update application state in a predictable and organized manner. It aims to provide a straightforward alternative to complex state management solutions, focusing on simplicity and readability. The core concept behind EvaluateState revolves around the idea of an "evaluator function." This function receives the current state and any arguments provided during an update, and it is responsible for returning the new state.

The library introduces a centralized store that holds the application's state. Developers define initial state and then create evaluator functions that describe how the state should change in response to specific actions or events. When an update is triggered, the corresponding evaluator function is executed, and its return value becomes the new state. This declarative approach ensures that state transitions are explicit and traceable.

EvaluateState also supports asynchronous operations. Evaluator functions can return Promises, allowing for the handling of operations like data fetching without blocking the main thread. This asynchronous capability is crucial for modern web applications that often interact with external APIs. The library's design emphasizes immutability, meaning that existing state is never directly modified. Instead, evaluator functions always return a new state object, which helps prevent unexpected side effects and simplifies debugging. Its lightweight nature makes it suitable for projects where a full-fledged state management library might be considered overkill.
