Before Day 1
4 Concepts to Master
You do not need to understand every line of code. These four concepts give you a simple way to start reading what is in front of you.
- Input
- What information does the code start with or receive?
- Action
- What does the code seem to do with that information?
- Output
- What result seems to come back?
- Decision
- Where does the code seem to choose between different outcomes?
How the challenge works
- Each day is one short challenge made up of several tasks.
- You may start with very little context. That is intentional.
- Nothing is graded, and you are never expected to understand every line.
- Treat the timed reads as practice.
