How did Redux come about?

Redux was created by Dan Abramov to address his needs for a better data handling architecture in JavaScript applications, particularly in large projects with complex data flows. While preparing for a conference talk, Dan was inspired by Flux architectures and React, but he sought a more predictable and maintainable system, which led to the inception of Redux.

Influenced by the Elm architecture, which originally introduced a pattern of reducer composition, Redux simplified the state management chaos of multiple stores found in traditional Flux architectures into a single state container. Abramov and his then-colleague Andrew Clark further refined Redux by promoting a functional programming approach where changes in the app's state are made using pure functions, thereby making it both predictable and testable.

This development of Redux was particularly fueled by the "conference-driven development" approach. Abramov was preparing for a talk at the React Europe Conference and wanted to provide a unique contribution. Redux was both a response to a personal challenge to find better solutions and an opportunity to share these solutions at a significant platform[1].
