Logic & Boolean Expressions — Part 15

Try it: run the code, then change it

1. 1Computers think in True and False. a > 3 asks 'is 5 greater than 3?' — yes, so it's True.
2. 2a > 10 asks 'is 5 greater than 10?' — no, so it's False. These True/False values are called booleans.
3. 3Other comparisons: == (equal?), != (not equal?), < (less than?), >= (greater or equal?). They all give True or False.
4. 4Booleans power every decision in code. Every 'if' statement checks a boolean. Every game checks: is the player alive? True or False!

Auto-run is on: change the code and the result updates by itself.
