I have a complex component with some "dynamic" imports.

I recreate my component tree on codesandbox: https://codesandbox.io/s/clever-rosalind-t3cfm?file=/src/App.js:298-302

I have an App.js file where I have a list of objects. Each object, render a RenderWidget component.

Inside RenderWidget, I need to get a "dynamic" comp. (I recreated that with a simple function, but i have more complexity in that part). So I wrapped the comp on useMemo to avoid component re-creation. (useMemo has a console.log to check if the Comp is re-initializated)

Inside the Comp, we have a useState declaration with the following initial value:

I have a ReactJS code (attached at the end of the post) where my objective is to find a good way to be able to "communicate" between some nested elements (I've tried to do a very simple code to explain my idea).

The columns are "hierarchy" based, so you have to active "A) Parent" before being able to active "A) Child 1". The main objective is to be able to "disable" (basically, set the state 'active' into false) an element when:

• Some element of a "different column" is active
• Some element of the same column and "depth" is active

Some examples based on the code:

• Disable 'A) Parent' when 'B) Parent' is turned active.
• Disable 'A) Child 1' when 'A) Child 2' is turned active.
• Disable 'A) Child 1' (and 'A) Parent') when 'B) Parent' is turned active.

In this last example, we are also disabling the "ancestors" (since this "works" as a nested structure, where you have to turn on A) Parent to be able to turn on A) Child X ).

As you can see, the idea is to work on a depth level.. Where when you "enter" in another "path", the current active path should be disabled.

I've been trying some methods, but none of them have worked properly. I think they are "expensive" and zero elegant.

My approaches have been something similar to this:

• Give a "depth var" on each element.
• Set a "current" var (useState) to App (root) and pass the "setCurrent" to each element.
• Use a "useEffect" hook inside each looking for changes on current.
• Then, conditionally try to manage them.

As I have said.. I'm pretty sure there are better methods to do this.. But I can't get with them.

Here is the code (for the example, I've tried to do the most simple setup without depth restriction, but remember that you have to "active" the ancestor before being able to "active" the descendant): https://codesandbox.io/s/optimistic-rosalind-1oykv?file=/src/App.js

Hello let's take this example :

I have a simple form and a field to render the value of that input field from that form

I'm learning Haskell and working on a Hamming distance exercise.

Good day guys! I want to do mouseover effect like in this video in my vue project. I tried some code but property transform changed just once. If someone knows, please help me. thats codesandbox.io code. I copied just a part of my code which doesn't work.

I have an application where I would like to print the location of the user similar to a breadcrumb. I have a component that I add at the application level and expect it to update with current value or the router.currentRoute object. However it doesn't seem to be updating as expected.

I'm using the Vue2 Composition api plugin and am trying hard to keep it in a decent state that will make migrating to Vue3 much easier once I'm able. This means I'd like to avoid using the context.$route object that's available. My attempt currently imports the router directly and wraps the currentRoute object in a ref() but that doesn't seem to work.

Here is a CodeSandbox with an application that shows the issue. I have a home page and two additional pages. The text that reads 'Your current location is: Home` should change to the name of the other pages when navigating there, however it does not change at all.

Premise:

I am currently working on the following problem:

I must find the index combinations of all occurrences of a substring in a string, where the substring is not necessarily contiguous.

My testing parameters:

I wanted to disable the check button after it click once and proceeding to next step. I try some other ways like adding the condition in methods but it doesn't work. can anyone guide me? Thank you.
