You see something is flawed in Redux at the point you have to pass strings (uppercase constants defined somewhere) around, import them in every file, pass them as identifiers of what you should do with each data.
There are also patterns to reduce the import issue. For example, https://github.com/erikras/ducks-modular-redux. I prefer defining my actions with my action creators in one big index, but the point is that there is absolutely a way to mitigate this concern if it bothers you :)
Well, that would be much worse, don't you think?
My point was that having to keep identifiers to everything is silly.
See the second line of the code snippet under "Symbols are completely unique…"
Unless I have misunderstood the spec, to compare symbols you require both the reference and value. Much more preferable than passing around Strings.
