I'm watching a tutorial about MERN stack project of a youtuber. And I'm watching him coding the Redux part of the project. There is some of his code which I don't understand This is his Redux action code to retrieve data from api [LINK] From what I understand, this is an action and it supposed to return action object {type, payload}.

I know similar questions have been answered multiple times over the years and I have scoured through just about all of them and can't seem to figure out what my issue is. I am getting the Cannot GET / error with NodeJS when opening the localhost:5000 in browser. When inspecting I can see it says "Failed to load resource: the server responded with a status of 404 (Not Found)", which I think may be related to my controllers file. Note: I am trying to code based off of this tutorial: [this video] The "This works" message previously showed up for me and the array symbol still shows up. It is the JSX structure part where I first run into this issue (begins at 28:50). I feel I have done exactly as the
