Good day.
I was testing stuff in Javascript with Proxies.
Currently I have this proxy
My question was, how do I iterate over this? I've tried several methods, including object.keys and forEach, which yielded nothing.
Thanks in advance

You need to specify an ownKeys method in the handler you're using to create the proxy or you won't be able to enumerate the keys of the proxy object.
const obj = { test: 'a' };
const handler1 = {
ownKeys(target) {
return Reflect.ownKeys(target);
}
};
const proxy1 = new Proxy(obj, handler1);
console.log(Object.keys(proxy1)) // ['test']
Edit
Actually, you can use Reflect.ownKeys directly also, but you'll want to make sure the behavior is what you expect. For example, it might return length as a key as well.

I am having trouble getting the property filename from the req.files that I get from the router. Here's what I get:
And here's how I've been trying to get the filename of each (I am only using 2 pictures in this example but I could get more than two images so that's why I am iterating with the forEach)
let arrayImages = [];
if (req.files) {
Array(req.files).forEach(image => {
arrayImages.push(image[0].filename);
})
}

Hi everyone thanks for all the help, i finally figured it out!
let arrayImages = [];
for (const clave in req.files) {
array = req.files[clave]
arrayImages.push(`${array[0].filename}`);
}
that way i've got the fieldname of each element

The root of your data from screen is an object.
So try to code like that:
let arrayImages = [];
if (req.files) {
Object.values(req.files).forEach(arr => {
arrayImages.push(arr[0].filename);
})
}

I created memory game. The only problem is that when the game is done and the player wins, it doesn't console.log('win)
Code:
let checkingImages = document.querySelectorAll('.card')
checkingImages = Array.from(checkingImages)
let check = checkingImages.every((each)=>{
each.classList.contains('matched')
})
if(check == true){
console.log('win')
}

Inside your every method, you're only checking for the class's existence, not actually returning anything.
You have to write it like this:
let checkingImages = document.querySelectorAll('.card')
checkingImages = Array.from(checkingImages)
let check = checkingImages.every(item => item.classList.contains('matched'))
console.log(check)
Or like this, if you want to stick to your original answer:
let checkingImages = document.querySelectorAll('.card')
checkingImages = Array.from(checkingImages)
let check = checkingImages.every((item) => {
return item.classList.contains('matched')
})
console.log(check)

envelope:'{"to":["reply-to-501-4455#email.ashishbhangade.com"],"from":"Tway"}'
here my object data and i want find values only 501 and 4455 (every time this values are dynamic not static values) so how to get please give me suggestion.

This is way to dynamic values
const split = '{"to":["reply-to-501-4455#email.ashishbhangade.com"],"from":"Tway"}'.split('-')
const code1 = split[2]
const arrWithCode2 = split[3].split('#')
const code2 = arrWithCode2[0]
console.log(code1, code2)
If "reply-to-" and codes length don`t change
const msg = '{"to":["reply-to-501-4455#email.ashishbhangade.com"],"from":"Tway"}'
const code1 = msg.substring(17, 20)
const code2 = msg.substring(21, 25)
console.log(code1, code2)

Perhaps with string.includes?
const envelope = {"to":["reply-to-501-4455#email.ashishbhangade.com"],"from":"Tway"}
console.log(
envelope.to.some(pr => pr.includes("501")),
envelope.to.some(pr => pr.includes("4455"))
)

i have a JS variable like this:
var elmnts = $('#elm1, elm2, #elm3, #elm4')
how can i add and remove other html elements?
i try this code but there is no result.
elmnts.add('#elm5');
elmnts.remove('#elm1')

$.fn.add returns new collection, it doesn't modify original one. So you should use this syntax.
elmnts = elmnts.add('#elm5');
To remove element from a collection of jQuery objects you can use $.fn.not method:
elmnts = elmnts.not('#elm1');
You should not use remove for this, it's used to delete element from DOM tree.
