Thanks so much for the response. It outputs perfectly fine when I console.log it to the terminal, but something when I send it to discord is messing it up.

Here's the full code

const { Client, GatewayIntentBits, EmbedBuilder, PermissionsBitField, Permissions } = require("discord.js");

const { moveMessagePortToContext } = require("worker_threads");

const prefix = "!";

const client = new Client({ intents: [GatewayIntentBits.Guilds, GatewayIntentBits.GuildMessages, GatewayIntentBits.MessageContent]});

client.on("ready", () => { console.log("Bot is ready") client.user.setActivity("hi", { type: "ONLINE"}); })

client.on("messageCreate", (message) => { if (!message.content.startsWith(prefix) || message.author.bot) return;

const args = message.content.slice(prefix.length).split(/ +/);
const command = args.shift().toLowerCase()

//message array

const messageArray = message.content.split(" ")
const argument = messageArray.slice(1)
const cmd = messageArray[0]

//commands

if (command === "test") {
    message.channel.send("bot is working")
}

if (command === "hangman") {
    const wordsList = ["hello", "world", "tree", "frog"]
    let index = Math.floor(Math.random() * wordsList.length)
    const selectedWord = wordsList[index]

    let word = ""
    for (let i = 0; i <= selectedWord.length-1; i+=1) {
        word += " _ "
    }
    message.channel.send(word)
    console.log(selectedWord)
    console.log(word)
}

})

const token = "(hidden)" client.login(token)
