2 numbers not adding together correctly - discord

Question

I'm using repl.it database for a discord economy bot that i'm making. I made a withdraw command, but when I type !withdraw 10 I'm expecting to receive currentbalance + amount (like if current balance is 50 and i typed !with 100 I should get 150) but I keep getting "50100". Here is my code:
if (message.content.toLowerCase().startsWith("#ايداع")) {
const args = message.content.trim().split(/ +/g);
let money = await db.get(`wallet_${message.member}`)
let currentbalance1 = await db.get(`wallet_${message.member}`)
let currentbalance = await db.get(`bank_${message.member}`)
let gembed = new Discord.MessageEmbed()
.setColor("RED")
.setDescription("ليس لديك مبلغ كافي للايداع")
let cembed = new Discord.MessageEmbed()
.setColor("RED")
.setDescription("يرجى تحديد مبلغ للايداع");
let amount = args[1];
if (!amount || isNaN(amount))
return message.reply(cembed);
await db.set(`bank_${message.member}`, currentbalance + amount);
await db.set(`wallet_${message.member}`, currentbalance1 - amount)
let sembed = new Discord.MessageEmbed()
.setColor("RED")
.setDescription("لقد قمت بايداع" + amount + "الى حسابك البنكي");
message.channel.send(sembed);
}

If your output is 50100 from 50 + 100 it means that your numbers (50 and 100) are strings not numbers. A simple solution would be to use parseInt.
Example:
let currentbalance1 = await db.get(`wallet_${message.member}`);
let currentbalance = await db.get(`bank_${message.member}`);
await db.set(`bank_${message.member}`, parseInt(currentbalance) + parseInt(amount));
await db.set(`wallet_${message.member}`, parseInt(currentbalance1) - parseInt(amount));
Full example:
if (message.content.toLowerCase().startsWith("#ايداع")) {
const args = message.content.trim().split(/ +/g);
let money = await db.get(`wallet_${message.member}`)
let currentbalance1 = await db.get(`wallet_${message.member}`)
let currentbalance = await db.get(`bank_${message.member}`)
let gembed = new Discord.MessageEmbed()
.setColor("RED")
.setDescription("ليس لديك مبلغ كافي للايداع")
let cembed = new Discord.MessageEmbed()
.setColor("RED")
.setDescription("يرجى تحديد مبلغ للايداع");
let amount = args[1];
if (!amount || isNaN(amount)) return message.reply(cembed);
await db.set(`bank_${message.member}`, parseInt(currentbalance) + parseInt(amount));
await db.set(`wallet_${message.member}`, parseInt(currentbalance1) - parseInt(amount))
let sembed = new Discord.MessageEmbed()
.setColor("RED")
.setDescription("لقد قمت بايداع" + amount + "الى حسابك البنكي");
message.channel.send(sembed);
