Redux normalized state

The basic concepts of normalizing data are: Each type of data gets its own “table” in the state . Each “data table” should store the individual items in an object, with the IDs of the items as keys and the items themselves as the values. Any references to individual items should be done by storing the item’s ID.26 Haz 2021

A normalized state is a way to store (organize) data . With this way each entity type will have its own place in the store, so that there is only a single point of truth. This practice is the recommended way to organize data in a Redux application as you can read in the Redux recipes.28 Şub 2022

When you need to put some control between what the user enters and the value that gets stored in Redux, you can use a “normalizer”. A normalizer is just a function that gets run every time a value is changed that can transform the value before storing .

By normalizing across this boundary, you are allowing data from the future (test set) to leak into the present (training set) . This can’t and won’t happen in the real world.
