Splitting a program into functions: Assembly Line

A messy machine gets split into clean stations, each a function with its own job and its own test.

What you'll learn

• Good function names
• One function, one job
• Splitting up a machine
• Checking your own work
• A function doing two jobs

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. A Better Name Change it
2. Pull It Out Copy and type
3. Two Stations Fill the gap
4. Test It Yourself Write it
5. Doing Too Much Fix it
6. The Whole Line Boss level

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