deck.js | Modern HTML Presentations

I am creating a flashcard app in React using hooks and having trouble deleting a deck of flashcards. I am able to render Bootstrap cards on the page with the flashcards name, description, card count, and the buttons as desired. However, I am unable to delete a deck of cards as I'm being told setFlashcards is not a function. Here is my code:

My "Card Dealer" in CodeSandbox

I was watching a coding challenge done in React with class based components that extracts data from a "card deck API" using Axios. Once you have the deck and the deck ID, you can then render a separate "Card" component that displays the current card and all previous cards.

Rather than use classes, I decided to try this challenge using hooks instead. Due to poor planning, my state is pretty much one big object, and I can't map over it to display multiple "Card" components. I only get the current stateless "child"card displayed at the moment.

How can I change the way I have my state structured so I can map over it to display the "image" prop for all the cards that were previously dealt to display simultaneously? Thanks for any input!

I wanted to be able to do something like:

I'm really suffering here due to some awful inconsistencies in importing/exporting modules in Node.js.

It's easier to see:

I have a chrome extension with chrome.debugger listening to all requests and responses on a site. It worked correctly on old chrome 62 but is broken after 73.

I used yarn to add an npm library called Swing to my project on Rails. https://github.com/gajus/swing

The problem is that, even though it is compiling successfully with the new library, I'm getting an error on the console and can't seem to be able to use the functions of the library.

I'm using webpack version 3.11.0 and Rails 5.1.5.

The code looks like this:

New rails project with template (includes gems: https://github.com/lewagon/rails-templates/blob/master/minimal.rb and Devise gem for authentication):

I have a React-Native flashcard app that boots with two tabs, a Home tab, and a New Deck tab. The Home tab is the default, and you can press or swipe over to the New Deck tab.

• The Home tab displays all of the decks the user currently has saved.

• On the New Deck tab, I have the user enter the title of their new deck and press a submit button. When that submit button is pressed, I re-navigate to the Home tab.

My issue is: How in the world do I trigger a re-render on the Home tab from a button press on the New Deck tab so the user can see the deck they just created?

I know I could use Redux to solve this issue, but no other part of the app is optimized in a "Redux" fashion, and I'd really like to not redesign the architecture of my app for the sole purpose of updating a single screen, mostly because this is the only instance where I would need this ability.

I've attempted to get around this by passing screenProps containing the this.forceUpdate method all the way from the StackNavigator component, but it didn't work. I also tried manually update the state of the App component to trigger a re-render, but the re-render never happened (although the state did update).

To gain a better understanding of Javascript ES6 and object oriented programming in general, I decided to try writing a simple Game of War.

At first glance, the game seems to run fine... it always returns the name of the winning player, and because it is a game of chance it seems to return any given player about 50% of the time.

However, upon closer inspection it appears that something is terribly wrong. The issue is that upon each successive turn, the total number of cards in the game is decreasing rather than staying at a constant 52.

The game utilizes five different classes, all listed below, and a war.js file that instantiates a game and logs the winner.

Run the game with node war.js

Card.js

So my goal is to have one react component that essentially lets you have a few of a child component if you press a button. I want to manage the state in the top-level component, and when you hit submit, I want the state of this component to essentially be an array of objects, one element for each component in the list. My idea for a solution was to render a couple of the child components and pass them an index. Then, I give them the upper-level onChange function for them to call with the index. The problem with this is that it works until I call this.setState in the upper-level onChange function. For some reason, calling this.setState causes my index parameter to always be the highest number index in the list of child elements.

Here is AddressesDataForm.js:

I've been trying to build a card game using Qt recently, but I come across a bug which is very weird.
