In Redux, “blind” is not an official term or concept related to its framework. If you’ve found the term in a certain context, it might be a typo, a nickname for a specific concept, or could be referring to something else entirely.
Redux itself is a predictable state container designed to help you write JavaScript apps that behave consistently across different environments and are easy to test. The main principles of Redux are focused around a single, read-only state managed by reducer functions and actions.
If you have heard “blind” in the context of Redux, it’s best to return to the original source or consult with the person who used the phrase.
