Making a flexible file path reader for discord.js using fs?

Question

I’ve been working for a while on making commands for my discord.js bot, but now I am starting to categorize them. My commands are currently being put into a collector for a new discord collection (named client.{commandType}commands). I want to make “{commandType}” to be changed out for the value “i” in the following code. Anyone know how to do this?

folder.forEach(i => {
  fs.readdir(`/home/runner/commands/${i}`, (err, file) => {
    if (err) console.log(err);

    let jsfile = file.filter(f => f.split(`.`).pop() === `js`);

    jsfile.forEach((f,e) => {
      let props = require(`/home/runner/commands/${i}/${f}`);

      client.commandPermissions.set(props.help.name, props.help.permissionLevel);

      console.log(`${props.help.name}: ${props.help.permissionLevel}`);

      client.{commandType}command.set(props.help.name, props);
             ^^^^^^^^^^^^^

    });

  });

});

So how do I fix that?

Edit: Just so I am clear, I am essentially trying to do this: client. + i + commands.set(props.help.name, props);

You should be able to just use:

client[i + 'command'].set(props.help.name, props);

Unlike many other languages, JavaScript has no difference between an object and a dictionary/hashmap. You are able to use either notation (obj.property or obj['property']) to access a property of an object. The main difference between them is that obj.property looks better, but in obj['property'], 'property' can be a normal string, a variable, or some other expression.

Hate to say it, but it didnt work. Gave me an error saying unexpected token ‘[’

The Guy with The Hat Over a year ago

@Silveradoz did you do client.[i + 'command'] or client[i + 'command']? The latter is the correct syntax.

I used both. Neither one worked sadly. Also, I’ll add a photo of the error.

@Silveradoz I just noticed, is it command or commands? You use both in your question, but I assume only one is correct.

That would be it (Hopefully)! I did use commands. I’ll test it and let you know. > Nope. Says the same error as shown in the top of the post... hmm... Also, am I properly tagging you? With your username I am not entirely sure...
