I am looking to improve the performance of my code through best practices and cleaner code.
My goal here is just to perform a conversion whenever there is a keyup.
But I noticed that my code looks very repetitive. In your view, what should I do to simplify it?
window.oninput = function(event)...
I've written this Card component which is composed of thumbnail image, name, symbol, total_volume, current_price, and price_change_percentage_24h.
I want to refactor my renderPriceChange function since it's using the same pattern.
const renderPriceChange = (price) => {
if (price > 0) {

I am trying to sort an associative array by following this scheme:
Sort by 'qt': positives first, negatives after
In positive part: sort by sa DESC
In negative part: sort by sa DESC
I managed to have the desired result but by tinkering :
$array = [
[
"id" => 1,
"qt" => 1000,...
This is a challenge from CodeSignal.
For
image = [[1, 1, 1],
[1, 7, 1],
[1, 1, 1]]
the output should be boxBlur(image) = [[1]].
To get the value of the middle pixel in the input 3 × 3 square: (1 + 1 + 1 + 1 + 7 + 1 + 1 + 1 + 1) = 15 / 9 = 1.66666 = 1. The border pixels are cr...
I am trying to translate the book Game Coding Complete by Mike McShaffry 4E to modern C++17 standard and faced with the code of Mersenne Twister by Takuji Nishimura and Makoto Matsumoto.
Is it right to convert random generator code from book like that:
from:
#include <ctime>
#define CMATH_N 624

Im planning to use Strategy design pattern to put it in
ScheduledExecutorService.scheduleAtFixedRate. I can use create as many scheduleAtFixedrate depends on the data to be pulled. Will this cause a race condition?

I have a medium sized project that uses a class hierarchy that essentially boils down to:
class Mach
{
public:
virtual ~Mach();
//...
virtual void common_action() =0;
//... A lot of common actions
//...
};
class MachStrato : public Mach
{
public: //...
// ...Implementat...
I'm struggling with strategy for my tests and I'm testing different approaches. As some part of my application needs connection to database I wanted to create tests that use mocks to avoid running special instance of database just for testing. That gave me a glimpse of how can I use mocks and I p...
This question is more architecture than code related.

I'm currently working on a fairly large web-targeted library, which I'm writing using TypeScript for my own convenience during development. Now that I'm close to wrapping up a release, I'm wondering what the ideal way to structure the ...
I have a use case where I try to initialize a Player object within a try block.
The relevant excerpt of the current, working code looks as follows:
string GameServer::processMapRequest(MapRequest const &request) const
{
MapResponse response;
response.header.playerId = request.header.playe...
I had a piece of code that solved really simple problem - it formated two dates to look better on a webpage. It looked like this:
function formatDateRange(
days: { firstDay: string, lastDay: string }
): string {
let first, last;
first = dayjs(days.firstDay); //dayjs parses string that for...
This question is a follow up of Header only bigint library written in c++20.
I've made all (or almost all) the corrections suggested in the answers, plus some minor change here and there and a modification in the division algorithm. Instead of a lot of constructors, now there are only two templat...
