This is either exaggeration or you just don’t get it, I usually end up with the same if not less code.
Here’s an example of a bad idea, say you have a redux store that you use for a form – allot of people would write an action for every field eg. UpdateFirstName, UpdateLastName etc… say you have 50+ fields, then obviously this is a huge amount of code. If your doing it this way then you need to stop writing code and think before you implement a solution.
Now let’s use that same example, but this time you have ONE action – updateField, in which you pass the name of the field you want to update into it.
