Javascript – How to remove commas on discord.js replies with map function?

I was doing this shop command for my discord server, and it’s suppose to show the shop items list one by one, but it’s not what’s happening, I don’t want it to reply the shop list with commas between the items, and I don’t know how to remove them, here is the code:

const { SlashCommandBuilder, EmbedBuilder} = require("discord.js");
const items = require("../shopitem")
const client = require("..");

module.exports = {
    data: new SlashCommandBuilder()
     .setName("shop")
     .setDescription("See the avaliable items to buy!"),
    async execute(interaction) {

        if (items.lenght === 0) {
        return await interaction.reply("There is no items here!", { ephemeral: true });
        }

        const shopList = items
        .map((value) => {
            return (`💵 ${value.price} - ${value.item}n`);
        });

        let embed_shop = new EmbedBuilder()
        .setTitle("**🛒|** ***Store:***")
        .setDescription(`${shopList}`)
        .setThumbnail(interaction.user.displayAvatarURL())
        .setTimestamp(Date.now())
        .setAuthor({
            name: interaction.user.username,
            iconURL: interaction.user.displayAvatarURL({ dynamic: true }),
             url: null
        })
        .setFooter({
        iconURL: client.user.displayAvatarURL(),
        url: null,
        text: `Sistema exclusivo ${client.user.username}®`
        })
        .setColor("#FF0090");
        
        await interaction.reply({ embeds : [embed_shop] });
    },
    
};

when i use the command it replies the embed correctly but the shop list stay like this:

💵 100 – Backpack
,💵 500 – Radio
,💵 1000 – Smartphone

and i wanted it to be like this, withou commas:

💵 100 – Backpack
💵 500 – Radio
💵 1000 – Smartphone

i expect to find a simple way to remove these commas since i’ve never used .map, and it’s my first time doing this, i have no idea of how the function works, just the basic

    In JS, when a array is converted to a string directly, it will join each item in the array with a comma (,). You can change this behavior by calling shopList.join(""). That will insert an empty string between each item in the array and return a single string.

    You can also join using other strings to join as well, such as a newline (n), like this: shopList.join("n")

    I think you want this

    .setDescription(`${shopList.join(" ")}`)

    let me know if that’s not it
