BoardStat | interactive NYC 311 dashboard built with Community Boards | Dashboard library

I am trying to make a simple 'Nonogram'/'Picross' game using React to learn UseContext and UseReducer, but am puzzled as to why my top component (App) is not re-rendering when a value it uses changes. Perhaps I am missing something basic, but I've read through documentation and examples online and can't see why it is not re-rendering.

Expectation: User goes on the application, clicks on the squares to change their value (draw a cross by clicking on the squares), and the text underneath the board reads "Congratulations!", as it is based on the value of 'isComplete'

Problem: As above, but 'Keep trying' remains.

I added a button to see the boardState as defined in the UseReducer function, too.

Code is as follows:

App.js

So, I was trying ato build a minesweeper with typescript and got stuck.

My problem is that my renderBody() function is not updating DOM when i change the boardState.

Can someone give me a light on my error here? I'm sure it's something very simple and I'm being stupid.

I want a loader element to show while my Sudoku solver function is running and hide upon completion. However, what happens in practice is that the loader never shows itself (or shows and hides almost instantly) even while the solver function is running.

I have an array in MIPS, and I'm trying to iterate over it.

This code works when I want to get the value of a specific array cell, but it throws a Runtime with address out of range 0x10565554 when I try to loop through it.

My application is storing the entire state of a "board" in the board component vie useState. I then map the state to create lists.

When I try to delete a list via an axios call, and then splice that list from my state, I am encountering an issue. The target list is not being deleted, instead the last list of the board is being deleted instead. Here is a quick screen recording of the issue: https://streamable.com/uarb97

As you can see from the alerts, everything is going as expected. I don't see why the wrong list is being spliced. here is my handleDelete function that is being passed from the board component to each list component:

I'm learning Vue.js with Vuex and TypeScript, in the application i'm building i came across the error "Object is possibly 'undefined'" in the Vuex Store.

The error happens in the "newCard" mutation in this line:

I have one HTTP endpoint which creates a map and stores it using Agent.

I want to access this map when I hit another endpoint. but when I a trying to get the data from Agent it is returning empty.

Can someone please confirm if this is a valid scenario for using Agents ? If yes, What am I missing ?

Simplified question is that I have array ['a', 'b', 3, 'c'] and I want to change 3 with null, null, null like this ['a', 'b', null, null, null, 'c'] how can I do it with Ramda?

this is my full code

Currently, I am trying to do a for loop for all the buses within the buslist, but after the first iteration, the code stops. If anyone can give me feedback on why this is happening I would be grateful
