The if keyword, as you can see down here on line 10, the if keyword is followed by a logical condition in parentheses. You can see there it's $x == 1. That double equals sign is the conditional test for equality and the condition is evaluated first, and if it's true the block of code is executed. And you see that block of code here starting with this curly brace ending with that curly brace on line 12. If the condition is not true, then the next line of code after the block is executed, and the code inside the block is never executed.
