    update.message.reply_text("Hello! I'm your Telegram bot.")

def main():
    updater = Updater(token='YOUR_BOT_TOKEN', use_context=True)
    dispatcher = updater.dispatcher

    dispatcher.add_handler(CommandHandler('start', start))

    updater.start_polling()
    updater.idle()

if __name__ == '__main__':
    main()

```
## Node-telegram-bot-api

If you prefer JavaScript, the node-telegram-bot-api library is an excellent choice for building Telegram chatbots. It simplifies working with the Telegram Bot API and offers robust features. Here's a basic example:

bot.onText(/\/start/, (msg) => {
    const chatId = msg.chat.id;
    bot.sendMessage(chatId, 'Hello! I am your Telegram bot.');
});

```

Telegraf is a modern and user-friendly Telegram bot framework for Node.js. It simplifies the bot development process and provides an intuitive API. Here's a simple example using Telegraf:

    public void onUpdateReceived(Update update) {
        // Handle incoming updates here
    }

    @Override
    public String getBotUsername() {
        return "YourBotUsername";
    }
