This might be symbolizing a ternary logic statement. The '?' comes after the conditional statement followed by the "if" and "then" portion. In your case, (condition) ? 2<=>1; The '<=>' is known as a Spaceship Operator Documentation here. 2<=>1 evaluates to 1 since 2 is greater than one and it's on the left side. So your statement here will echo (or print to the console) "1" if the condition is true. Hoped this helped!!!
