Questions tagged [redux]

Redux is an innovative approach and framework built to effectively handle the state of JavaScript applications. By utilizing dynamic events known as "actions", it offers a centralized storage solution for state management throughout your entire application. With defined regulations in place, Redux ensures that state updates occur in a reliable and predictable manner. This tool greatly simplifies your understanding of when, where, why, and how the state within your application evolves, as well as the consequent behavior of your application logic following these modifications.
