so here is an object
{
can: ["a", "b", "c", "d"],
votes: [12, 21, 30, 25]
}
and I want the result to be like this
`<div>
<div>a</div> <div>12</div>
<div>b </div> 21</div>
`
and so on…
I tried different combinations of Object.keys() and Object.enttries() but none worked for me.
I am trying to rewrite the url based on the locale retrieved from my middleware.js, however, the url is not rewritten and returns a page-not-found 404. However, when I go to “localhost:3000/en” for example I get the correct response and everything works as expected. What am I missing here?
middleware.js
import { NextResponse } from "next/server";
import { match } from "@formatjs/intl-localematcher";
import Negotiator from "negotiator";
let locales = ["en", "ka", "ru"];
export let defaultLocale = "en";
function getLocale(request) {
const headers = new Headers(request.headers);
const acceptLanguage = headers.get("accept-language");
if (acceptLanguage) {
headers.set("accept-language", acceptLanguage.replaceAll("_", "-"));
}
const headersObject = Object.fromEntries(headers.entries());
const languages = new Negotiator({ headers: headersObject }).languages();
return match(languages, locales, defaultLocale);
}
export function middleware(request) {
let locale = getLocale(request) ?? defaultLocale;
const pathname = request.nextUrl.pathname;
const newUrl = new URL(`/${locale}${pathname}`, request.nextUrl);
// e.g. incoming request is /products
// The new URL is now /en/products
return NextResponse.rewrite(newUrl);
}
export const config = {
matcher: ["/((?!_next|api|favicon.ico).*)"],
};
file structure
src
-app
--[lang]
---(public)
----layout.jsx
----page.jsx
the problem appears to be having everything in my src folder. Moving my app directory into the root seems to fix the problem? Why would this be causing an issue?
I want to see how useMemo and useCallback hooks works inside for my research purposes. Like how they work under the hood. How can I?
I tried to go inside main React file but all I found was just a namespace declaration for these hooks

I’m encountering an error while setting up opentelemetryio’s development environment (https://github.com/open-telemetry/opentelemetry.io)(https://github.com/open-telemetry/opentelemetry.io/blob/main/CONTRIBUTING.md) (https://github.com/open-telemetry/opentelemetry.io/blob/main/package.json)using npm. Here’s the output:

The error seems to originate during the postinstall.js script execution within the hugo-extended package. I’ve tried the following troubleshooting steps (if applicable):
Cleared npm cache (npm cache clean --force)
Reinstalled dependencies (npm install)

I have some working code to manipulate a Sqlite database written in this notation (I think ES5?):
try {
const cols = Object.keys(data).join(", ");
const placeholders = Object.keys(data).map(x => "$" + x).join(", ");
const stmt = db.prepare(`
INSERT INTO ` + table + ` (` + cols + `)
VALUES (` + placeholders + `)`);
stmt.run(data);
} catch (err) {
// some reporting and handling
}
Where the values to populate the SQL statement come from a JS object (data) passed on earlier.
I would like to refactor this to use ES6 and replace the try...catch block with arrow functions. I found some examples (here and here) but they use a different syntax, where the SQL command is executed directly with the .run() method, instead of using .prepare() as I have in my code.
However, when I try to apply an arrow function directly to my code
const cols = Object.keys(data).join(", ");
const placeholders = Object.keys(data).map(x => "$" + x).join(", ");
const insert_stmt = db.prepare(`
INSERT INTO ` + table + ` (` + cols + `)
VALUES (` + placeholders + `)`);
insert_stmt.run(data, (err) => {
if (err.message === "some error") {
// handle the error
}
});
I get the error
TypeError: Named parameters can only be passed within plain objects
From what I could understand, this is probably a syntax error? Which I think means with the new notation I’m not passing the values within the data object correctly.
What are the best practices in a situation like this? Should I abandon the .prepare() syntax and go with the examples in the webpages I linked?
I was trying to download this file off of github because I wanted to try to learn some javascript https://github.com/rohan-paul/Awesome-JavaScript-Interviews/blob/master/Javascript/ES6-Array-Helper-Methods/destructuring.js
it gets marked as a virus by windows defender
This is what windows defender marks the javascript file as malware
Anyone know why this is happening to me?
If I turn off windows defender and download the file it cant mark it as malware but if I turn it back on and open the javascript file it removes it
On https://lumalabs.ai/ there’s a nice animation with particles moving dynamically relative to your cursor movement. On the Luma text on the front page. Does anyone know in which way I could achieve something similar? I usually use Angular for my projects
I have a GET API from azure that generates a token when the page loads. and I need to connect it with my react app. I tried the API first on Postman, everything worked successfully and I got a generated token. After that, I used axios to connect with the API in my react app. But everytime I get this error message that says “Access to XMLHttpRequest at ‘https://myTokenAPI/api/[email protected]’ from origin ‘http://localhost:5173’ has been blocked by CORS policy: Response to preflight request doesn’t pass access control check: It does not have HTTP ok status.“

1- I tried to contact with the IT of the company that made the API, and he said that it’s working with others normally.
2- I tried to use https with my localhost server using mkcert, and nothing changed
3- I tried to upload the app on a real domain, sorry for not sharing it because it contains private information, and agian nothing changed.
4- I tried to use JavaScript fetch, agian the same error.
5- I tried to use Jquery, I wasn’t sure about the correctness of the code, but the same error appeared.
6- i tried to take the code out of the useEffect react hook, and nothing changed, the same error 🙁
This error is showing up only when I have 2 different files for html and js. even if i add ” document.addEventListener(‘DOMContentLoaded’, function() {
countEl.addEventListener(“click”, increment);
});”
Given below are the code
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
<script src="./index.js"></script>
//<link rel="stylesheet" href="./index.css">
</head>
<body>
<h1>People entered:</h1>
<h2 id="count-el">0</h2>
<button id="increment-btn" onclick="increment()">INCREMENT</button>
<button id="save-btn" onclick="save()">SAVE</button>
</body>
</html>
let count = 0;
let countEl = document.getElementById("count-el")
function increment() {
count = count + 1;
countEl.innerText = count;
}
increment();
function save(){
console.log(count);
}
document.addEventListener('DOMContentLoaded', function() {
countEl.addEventListener("click", increment);
});
it either shows error for the line “countEl.innerText = count;” or for “INCREMENT” and “SAVE” button, the error shows for button if i remove listners is “Uncaught ReferenceError: increment is not defined” i want to make this work in two different file ie, html and js two seperate files. Refer to the image as well.
enter image description here
when click on increment button every time the count should be added +1. and when click on save the count should stop with the last cilcked number.
I’m having a problem with my tensorflow code, it won’t output anything about the prediction and losses of my model. here’s the code
const model = tf.sequential();
model.add(tf.layers.dense({ units: 4, inputShape: [3], activation: 'sigmoid' }));
model.add(tf.layers.dense({ units: 3, activation: 'sigmoid' }));
model.compile({
optimizer: tf.train.sgd(0.1),
loss: "meanSquaredError",
});
const input = tf.tensor2d([
[1,0],
[0,0],
[0,0],
]);
const target = tf.tensor2d([
[5],
[0],
[0],
]);
train().then(() => {
console.log("training complete");
const prediction = model.predict(input);
prediction.print();
});
async function train() {
for (let i = 0; i < 100; i++) {
const response = await model.fit(input, target, {
epochs: 20,
shuffle: true,
});
console.log(response.history.loss[0]);
}
}
I’ve tried tweaking, put random values in the arrays (inputs outputs) but I never got my expected results! which is just some loss value and the goal data
can you please see what’s wrong with my code?
thanks
I have a random increase for a bunch of variables, I used setIntervel() to have something like a live update for the variables but they don’t seem to update:
const no= document.getElementById("no");
const ni= document.getElementById("no");
const nu= document.getElementById("no");
const ny= document.getElementById("no");
const nt= document.getElementById("no");
const visit = document.getElementById("visited");
let a = sessionStorage.getItem("a") ? parseInt(sessionStorage.getItem("a")) : 1;
let b = sessionStorage.getItem("b") ? parseInt(sessionStorage.getItem("b")) : 1;
let x = sessionStorage.getItem("x") ? parseInt(sessionStorage.getItem("x")) : 1;
let y = sessionStorage.getItem("y") ? parseInt(sessionStorage.getItem("y")) : 1;
let z = sessionStorage.getItem("z") ? parseInt(sessionStorage.getItem("z")) : 1;
let display;
no.onclick = function(){
sessionStorage.setItem("a", a + 1);
window.location.href = "no.html";
}
ni.onclick = function(){
sessionStorage.setItem("b", b + 1);
window.location.href = "ni.html";
}
nu.onclick = function(){
sessionStorage.setItem("x", x + 1);
window.location.href = "nu.html";
}
ni.onclick = function(){
sessionStorage.setItem("y", y + 1);
window.location.href = "ny.html";
}
nt.onclick = function(){
sessionStorage.setItem("z", z + 1);
window.location.href = "nt.html";
}
function update(){
if(a > b && a > x && a > y && a > z){
display = "Popular Now: no";
visit.textContent = display;
}
else if(b > a && b > x && b > y && b > z){
display = "Popular Now: ni";
visit.textContent = display;
}
else if(x > a && x > b && x > y && x > z){
display = "Popular Now: nu";
visit.textContent = display;
}
else if(y > a && y > b && y > x && y > z){
display = "Popular Now: ny";
visit.textContent = display;
}
else if(z > a && z > b && z > x && z > y){
display = "Popular Now: nt";
visit.textContent = display;
}
}
setInterval(() => {
let i = Math.floor(Math.random() * 5 + 1);
if (i === 1) {
sessionStorage.setItem("a", parseInt(sessionStorage.getItem("a") || 0) + 1);
} else if (i === 2) {
sessionStorage.setItem("b", parseInt(sessionStorage.getItem("b") || 0) + 1);
} else if (i === 3) {
sessionStorage.setItem("x", parseInt(sessionStorage.getItem("x") || 0) + 1);
} else if (i === 4) {
sessionStorage.setItem("y", parseInt(sessionStorage.getItem("y") || 0) + 1);
} else {
sessionStorage.setItem("z", parseInt(sessionStorage.getItem("z") || 0) + 1);
}
update();
}, 5000);
The live update should occur right after the values increase meaning that it isn’t using outdated values, yet I have to manually reload the page to see the change, and if anybody can offer a more random way of adding to the values I would like to know it, also don’t mind the weird variable and button names, it is not something I would like to share online, Thanks.
I was expecting a live update for the popular now part
Now I have the below code for me to draw the triangle, but the shape expand direction is not what I want. I would like to have the equilateral triangle expand symmetrically from the mouse position. How should I adjust this?
function DrawTriangle() {
this.icon = "assets/triangle.jpg";
this.name = "DrawTriangle";
this.color = "black"; // Default color is black
var startTriX = -1;
var startTriY = -1;
var drawingTri = false;
this.draw = function() {
if (mouseIsPressed) {
if (startTriX == -1) {
startTriX = mouseX;
startTriY = mouseY;
drawingTri = true;
loadPixels();
} else {
updatePixels();
stroke(this.color); // Set the stroke color to the selected color
strokeWeight(5);
// Calculate the height of an equilateral triangle
var triHeight = (mouseX - startTriX) * Math.sqrt(3) / 2;
// Draw an equilateral triangle using the mouse position as the third vertex
triangle(startTriX, startTriY, mouseX, mouseY, startTriX + (mouseX - startTriX) / 2, startTriY + triHeight);
noFill();
}
} else if (drawingTri) {
drawingTri = false;
startTriX = -1;
startTriY = -1;
}
}
}
My program logs in (in login.html) and the express session cookie is created. Once the page is switched to index.html, the cookie is lost. I am using the live port extension running of port 5500 vscode and I am using node with mongo running on port 3000.
Here is the code snippet.
const corsOptions = {
origin: 'http://127.0.0.1:5500', // Set to your frontend's origin
credentials: true, // To allow cookies and sessions
};
const app = express();
app.use(cors(corsOptions));
app.options('*', cors(corsOptions));
app.use(express.json());
app.use(cookieParser());
app.use(session({
secret: 'secret',
resave: false,
saveUninitialized: true,
cookie: {
path: '/',
httpOnly: false, //cahnge later to true
secure: false, // For development. Use 'true' for production with HTTPS.
sameSite: 'none',
maxAge: 1000 * 60 * 60 * 24 * 365
}
}));
I have tried adding the path, changing the sameSite to Lax, changing the max age, adding credentials. To add on, my back end works perfectly fine with Thunder Client. The cookie is stored and I can use a post to retrieve the user data.
I am using Ioredis client in JS for redis cluster. When I use scaleReads: “slave”, read queries are sent to a slave node. But when there multiple slave nodes for a single key, then a random node is choosen.
How do I load balance the read requests to all the slaves for a master or is this concept of choosing a random node enough to distribute load?
Please suggest some ideas
