Understanding Redux

With the great prevalence of web applications and companies transforming from traditional desktop-based systems to web-based systems, there are now a multitude of opportunities on the World Wide Web. There are various programming languages for server-side scripting (SSR), client-side scripting, presentation logic (HTML and CSS), and query languages. JavaScript is one of the most popular languages on the web, and it encompasses several frameworks that assist in its development, compilation, and production.
