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.

    SLACK_BOT_TOKEN=your_slack_bot_token
    SLACK_APP_TOKEN=your_slack_app_token

2. run the program:

    go run main.go
   

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