Boop | scriptable scratchpad for developers

I'm using discord.js and here is my code:

I need to get the longest surname from this array and return it.

Some of my discord bot's event listeners stopped working for some reason. Basically i have only two of them: 'guildMemberAdd' event works as intended but 'message' doesn't. Bot simply doesn't recognise !commands sent to it.

My closest assumption is that i messed up sync / async functions.

My main bot.js file:

I want my bot to post a simple welcome message in a 'welcome' text channel for every new member.

I've read a lot of posts here and there but still having trouble with making it work as intended

Here is the code:

I wrote the following code to attempt to translate between English and Morse code:

The component I have has a list of names with an add button beside each

I have created a basic application with a working function array that is supposed to take a user's input, and return an array with their input as the last number in the array- replacing certain integers with strings in the process.

When I console.log something like rangeOfNumbers((0,13)); it shows everything functioning properly. However, I have tried googling everything, looking at MDN, and sitting at my computer for hours trying to figure out how to implement my function into the UI so that it will print when the user hits submit, but I just cannot figure out what to do next or what I am doing wrong.

Console logging it works, but I don't understand why the user's input isn't being pushed into the end of the array automatically with the function. If someone could help this beginner out, it would be greatly appreciated. Thanks!

Here is the block of code in my scripts file that I am struggling with:

I am new to javaScript and struggle a bit with looping and writing functions. I am trying to come up with a function that cycles through my rangeArray where the users inputted number is the end of the array, and each integer that includes 1 is replaced with "Beep" up to that users inputted number. Ex: [ 0, "Beep", 2, 3, 4, 5, 6, 7, 8, 9, "Beep", "Beep", 12 ]. 12 and 2 will be different because later I intend on adding an exception where if a number includes any integer of 2, it supersedes the "Beep" and will replace it with "Boop". Does anyone have any idea how this function would be written? So far I've attempted writing a .includes or even using splice but so far I have only been able to replace the number 1 and nothing else. Help would be much appreciated! Thank you :)

Here is my code so far:

Is there a way to pass dynamic data to the Stripe API? I'm using the example found here: https://stripe.com/docs/payments/checkout/client

I'd like to be able to pass a token along with the purchase in order to link an account with that payment. After the client side sends the payment to the API, my backend would receive the details of the payment, including the token to link it to an account created before this. I would add it as a param to to the successful redirect, but if they close the window early then the accounts will not be linked. I set up my product using the dashboard.

I tried using metadata and description as a part of the line item, but it keeps saying "Invalid stripe.redirectToCheckout parameter: lineItems.0.description is not an accepted parameter."
