Is there a good current resource for 2019 on react/redux?

Question

Frontend

I'm trying to pick development with react / redux, but a lot of things are outdated.
Actually, maybe someone knows a good resource on this topic, apart from official sites and documentation, you need a good roadmap for this stack.

Nice course on react. If you are only interested in the react + redux bundle, or only redux, then you should watch the course from the middle.

You just need to understand the essence, understand how HOCs (higher order components) and the props projection work. In short, a readax is a single store that does not allow you to change data directly, instead you need to dispatch actions that are thrown into reducers - pure functions whose task is to get the current state of the store and the action as input, make changes without affecting the current state (immutable) and return a new state. Reducers are called in a chain, and middleware are also called in a chain, which allow you to intercept actions and, for example, perform asynchronous actions, such as API requests. And finally, any component can subscribe to changes in the store using HOC connect from the react-redux package.
If the above is clear, it remains only to practice. I recommend that you start by describing the store and reducers with actions, and then just twitch the dispatch actions directly, without any react.
Well, to make life easier and increase the performance of the application, you also need to understand reselect (memoized selectors) and just to make it completely fun immutable - immutable data structures that return a new structure with a new link for any sneeze, due to which any changes are detected through a banal link comparison .
reselect and immutable are like spices, they allow you to significantly optimize the application, but at first you can live without them.

And what certificates or tests can I take online so that I can post a link in my resume?
