Slack Age Calculator 🎂

This Go program calculates a user's age based on the year of birth (yob) provided in a Slack command. The program utilizes the slacker library for Slack bot development and reads environment variables from a .env file.

Usage 🚀

  1. Create a .env file in the project root with the following format:

     SLACK_BOT_TOKEN=your_slack_bot_token

     go run main.go

The bot will listen for commands in Slack and respond with the calculated age.
