Doubt about MD explanation

Yep, nice catch. Thanks!

Sorry to bother you again with these doubts, but I keep getting caught...

I read about your explanation on "Actions vs. Action Creators" in the README.md file inside 'actions' folder and then I ended up concluding that reducer-users.js file is an action creator... am I right? or I just got confused...

Thanks in advance!

[buckyroberts]

No problem.

Not exactly. Action creators are the function, and actions are the return value of that function. Think of it like this:

function actionCreator() {
    return action;
}

Actions are just like announcements, they don't really do anything in terms of changing or manipulating any data in your program. They just let the reducers know that "something just happened".

A reducers job is to basically wait and listen for these announcements (actions) to occur. Once it hears one, it decides how the programs data should be changed. So basically:

• actions are announcements
• reducers listen for these announcements, and then can change data/do anything else as a result

Thank you, Sir. I'm trying to stay in the same page.

So, here comes another one: index.js inside dev/js path is going to DOM, so we find the next statement in Line 3:
import ReactDOM from "react-dom";

However, after looking at real-world redux official example, I found that they call render function directly, using this statement instead:
import { render } from "react-dom";

Here I found some answer:

This is by design – it’s much better and you’re encouraged to import just the functions you need to use.

Ok. I shouldn't be thinking about just merely syntax sugar, but I still wonder if we should be aware about some subtle improvements besides saving a few characters. Are we getting better performance? Saving some memory? Is it just a good practice to get more concise or cleaner code? Does it really matter to bother you with bananas and mango?

Yep, that is just a different way you can import functions from external modules in ES6. It does make the code a little cleaner, you just have to watch out for naming conflict (for example if more than one module had a render() function)

If you see any areas for improvement, feel free to submit a pull request to the repo. Check this cheat sheet out too, I always refer to it when working with ES6!
