JavaScript Promise in 100 Seconds
Why Stack Overflow recommends it
Stack Overflow users link it when an asker's problem comes from not understanding promises and a quick visual primer is more useful than long documentation.

What it is
A very short explainer from Fireship that covers what a JavaScript Promise is, the pending, fulfilled and rejected states, and how to consume them with then, catch and async/await. It runs under two minutes and is part of the 100 Seconds of Code series.

It's hard to choose, there are plenty of resources. MDN Docs [LINK] would probably be the most trusted source, but if you're looking for a shorter read, it looks like this one [LINK] is fine. If you're more of a visual learner, I'm sure you'll find some good videos about them on YouTube. This one [this video] is really short and well made

Ok, I edited my answer. If you don't know how promises work, maybe this 100 seconds YouTube video [this video] will help you understand

Welcome to stack overflow, the problem in this case is you are using promises to get the downloadUrl, but you are returning the imgs array before that. In this case you could map each image to a promise, and await Promise.all to resolve all of them, giving you the expected array. If you don't understand promises I recommend watching this short video [this video] . Here is the altered code export const saveImages = async (images) => { try { const imgs = await images.map(async (image) => { const imgRef = storage.ref(`Works_Realized/Images/${image.name}`).put(image); imgRef.on( "state_changed", snapshot => { }, err => { console.log(err); }, () => { const imgUrl = await storage .ref('Works_Realized/I

Please check this video for understanding what the promise is, I think it's explained in a super clear way: [this video]

Welcome to Stack Overflow! You're not awaiting the response and so that's why the state is pending . $promise = Http::async()->get(' [LINK] ')->then(function ($response) { echo "Response received!"; echo $response->body(); }); echo "The request has been sent, but we didn't wait for the response."; The code above is referenced from here [LINK] Fireship.io also has a great video explanation on this here [this video]

So from what I understand, your native component Aes has 5 functions: pbkdf2, decrypt, encrypt, randomKey and hmac256. A more flexible and readable way to do what you want is using async await on each "promise" function. So basically I would do this: const Encrypt = (message) => { const Aes = NativeModules.Aes const options = { password: "Password", salt: "salt", cost: 5000, length: 256 } const generateKey = (password, salt, cost, length) => { return Aes.pbkdf2( password || options.password, salt || options.salt, cost || options.cost, length || options.length ) } const decryptData = (cipher, iv, key) => Aes.decrypt(cipher, key, iv) const encryptData = async (text, key) => { const iv = await
Cites Speykious · 2020-09 · Stack Overflow · on “How could I show the info of a mentioned user inside of this embed? Discord.js”
So if I understand correctly, in your current code, what you do is show the information of the author of the message. And what you want to do is to be able to show the info of a user who has been mentioned in the content of the message, when a mention is there. Alright! First, know that a discord mention is of the following form: <@!012345678901234567> , where the bunch of numbers is the ID of the user you have mentioned. I presume your command would either look one of two ways: ${prefix}user ${prefix}user <mention> Thus, instead of checking the exact value of the message, check the beginning of the content, and then if there is a remaining argument. Also, if you mention someone, you have to
