如何根据 discord 消息更改变量？

Question

I am working on a discord bot, and I am trying to change variables based on user input. The code should function a little bit like this:

const w = "something";
const r = "something else";
var a1 = w;

execute(message, args){
    if (!args.length){
        message.channel.send("no arguments");
    } else {
        var args[0] = args[1];
    }
}

What I want to happen is that when a user in discord types

!command a1 r

that the variable a1 changes to "something else". How can I do this?

You can use Object / Map here, instead of variables

Something like:

const consts = {
  w: "something",
  r: "something else"
};

const variables = {
  a1: consts.w
};

execute(message, args){
    if (!args.length){
        message.channel.send("no arguments");
    } else {
        variables[args[0]] = consts[args[1]];
    }
}

However, I'm not sure what you trying to do its good practice. Using mutable variables is a big window for bugs, especially if the user can change it.
