Challenge Information

Ship It or Sink: The Dev vs. Prod Toggle Script

Release imminent! Boss 'Captain Deadline' yells: 'SHIP IT OR WE SINK!'

You have one bash script with markers: #DEV_ONLY and #PROD_ONLY.

Rules:
- #DEV_ONLY → comment out (add leading #).
- #PROD_ONLY → uncomment (remove leading #).
- Both → Prod wins (line stays active).

Fix it in five minutes or suffer a 200-slide Lunch 'n Learn on our release process.
