Lesson 44 of 79 · 15 minutes

Scope: where variables live: Hotel Rooms

Each function is a room. Whatever is left in a room can't be reached from the corridor, unless it's handed out.

What you'll learn

• Each function has its own boxes
• Handing a value out
• The same name in two rooms
• In through the door, out through the door
• A change that gets lost

Each idea opens with a short narrated video, about 2 minutes in all. Then you put it to work in the game.

The six levels

1. Two Guests Change it
2. Through the Door Copy and type
3. Same Key, Different Room Fill the gap
4. Upgrade Points Write it
5. The Lost Point Fix it
6. Check-In Desk Boss level

The levels go from changing one word, to writing the code on your own. The boss level changes every time you play.
