I'll help you create a WhatsApp bot for a group chat using the whatsapp-web.js library. Let's start with a basic implementation that you can later customize based on your specific needs.
whatsapp-bot.js
This is a basic WhatsApp bot for group chats. Here's what it does:
Listens for messages in groups and responds to specific commands:
!ping - Responds with "Pong! 🏓"!help - Shows available commands!info - Shows information about the groupYou can extend this bot by:

I see the error - the packages aren't available in this execution environment. Let me provide you with a code example that you can save and run locally after installing the required packages.
Here's a complete WhatsApp group bot implementation that you can save to a file and run after installing the dependencies:
whatsapp-bot.js
Before running the bot, you need to install the required packages. Create a new directory for your project and run these commands:
# Create a new directory and navigate to it
mkdir whatsapp-bot
cd whatsapp-bot
# Initialize a new Node.js project
npm init -y
# Install the required packages
npm install whatsapp-web.js qrcode-terminal
# Save the code above to a file named whatsapp-bot.js
# Run the bot
node whatsapp-bot.jsThe bot responds to these commands:
!ping - Responds with "Pong! 🏓"!help - Shows available commands!info - Shows information about the groupWould you like me to explain any specific part of the code in more detail?
