   One of the biggest issues in React that I have come across is that you have to make copies of objects and arrays (as mentioned in this article) when calling setState(). Cloning works well for small arrays and objects (I use the code below f

   Incorrect. In fact, you can use React as the 'V' in MVC. That's how it was orignally designed. See here: https://github.com/facebook/react/tree/015833e5942ce55cf31ae... I am done with this thre

   I think you're thinking of MVVM, not MVC.

   So you're building business logic into your view components? This used to be simple in the old days when we used MVC.

   It is idiomatic JavaScript. If you learned Java at the university you'll immediately be comfortable with the code. Now consider React with hooks. It is neither OOP nor functional and it looks alien to anyone who knows idiomatic Java or

   The timing hack is a workaround for a browser bug. The exact same hack would be required in React as well. What is this browser bug I speak of? Browsers send a spurious "hover" event when you stop scrolling, so that the item under

    That would be cool, if true. I would like to see what the underlying query looks like, and whether it is efficient.

    In your home screen ( https://www.plato.io/ ) the screenshot has a Purchase column that has multiple values. Does that not violate 1NF? The first normal form (1NF) requires that each column in a table must hold atomic (indi

    But there must be a limit to how many rows you can display on screen efficiently, right?

    What is the maximum number of rows supported? What data types are supported? Do you support images and attachments?

    Can you clarify what you mean here? What state is in DOM? Do you mean the state inherent in input elements? What timing hacks are you talking about?

    None of that is true in React hooks. The negative sentiment towards hooks that you see here is because it is weird and complicated. Want to see how much simpler code can get when you code without React or any such fat frameworks? Take a loo

    Why is it necessary to use FP to write software that runs in web browsers? To be sure, FP has benefits (such as, it is much more straightforward to reason about FP code), but those benefits are not applicable in React. So why pretend it is

    I think you may be missing the forest for the trees. The point of FP is that you can glance at a function and say 'this is obviously correct' without having to work out the state and context of every call.

    Don't call this functional programming. If you call setCount() then this is not functional because your function is doing something besides returning a value. In fact, it is setting state, which is against FP principles.
