What you'll learn in this Go control flow tutorial

This interactive Go tutorial has 12 hands-on exercises. Estimated time: 18 minutes.

1. Your first decision — Imagine a bouncer at a club. They check your age. If you are old enough — you get in. If not — you don't.
2. Comparison operators — The condition inside an `if` uses comparison operators to check relationships between values.
3. if-else — two paths — An `if` runs code when the condition is true. But what about when it is false?
4. else if — more than two paths — Sometimes two options are not enough. What if you need A, B, C, D, or F?
5. Logical operators — combine conditions — Sometimes one condition is not enough. What if you need two things to be true at the same time?
6. switch — cleaner decisions — When you have one variable and many possible values, a long `else if` chain gets messy fast.
7. Multiple values in one case — Sometimes several different values should do the same thing.
8. switch with no condition — A `switch` does not need a variable to compare. Without one, each case acts like an `if` condition.
9. Short variable declaration in if — Go lets you declare a variable right inside the `if` statement.
10. Nested if — a decision inside a decision — Sometimes you need to check one thing, and only if that passes, check something else.
11. Fix the broken logic — This program is supposed to check if someone can drive.
12. Build a decision machine — No starter code.
