如何从discord.js中的Collection Map获取数据

Question

For my bot in discord, I would like a !help command that loops through all commands, gets the name, and returns them in a message back to the user. I have created fs to loop through my /commands/ folder:

for (const file of commandFiles) {
    const command = require(`./commands/${file}`);
    client.extraCommands.set(command.name, command);
}

console.log(client.extraCommands);

Returns a Collection Map that looks like: (cropped for sake of simplicity)

Collection [Map] {
  'args-info' => {
    name: 'args-info',
    execute: [Function: execute]
  },
  'channel-info' => {
    name: 'channel-info',
    execute: [Function: execute]
  }

All I need is to store the name of each command into an array.

I've tried looping through to get the key but that doesn't seem to work...

Thanks in advance for any help

Answer 1

看起来键名是你的命令名，所以这应该可以解决问题。

let keys = Array.from(client.extraCommands.keys());

Answer 2

Both lines of codes will return the same result as you want.

[...client.extraCommands.keys()] //using map keys
[...client.extraCommands.values()].map(({name})=> name); // using key 'name' from each map value

Answer 3

So, at first, I thought I should make a loop to go through all files and get the 'name' attribute. However, the .keys() returns an array for all properties inside the map Documentation
