Listing one array next to another in one message

Question

I have two arrays and I want to list in one entry of Array 1 next to an entry from Array 2.

My two Arrays are named memberIDs and rolesIDs. Whereas memberIDs contains the IDs from member in a voice Channel, roleIDs lists a ton of IDs from different roles. To list them next to each other I made the following code:

message.channel.send(memberIDs.map(element => "<@" + element + "> -> " + rolesIG.map(element => "<@&" + element + ">" ).join()).join("\n"));

Sadly it isn't working like I want it to, although it lists all member seperatly, on the other site it lists all entrys from roleIDs like this:

<@memberID1> -> <@&roleID1> <@&roleID2> <@&roleID3>

<@memberID2> -> <@&roleID1> <@&roleID2> <@&roleID3>

It want it to behave like this:

<@memberID1> -> <@roleID1>

<@memberID2> -> <@roleID2>

I apprectiate any help.

Answer 1

You could do something like:

var outarr = []
for(var i = 0; i < memberIDs.length; i++) {
  outarr[i] = `<@${memberIDs[i]}> -> <@${rolesIG[i]}>`
}

now outarr is a list, where each item contains the member ID concatenated with the roleIG
