QUIZ: Is it Even or Odd?
QUIZ: Is it Even or Odd?

The Challenge!
Alright, tech wizards! Let’s fire up those brain cells with a classic: Even or Odd! But here’s the catch: we’re diving deep into the modulo operator (%).
Quick refresher: The modulo operator (%) returns the remainder of a division. For example, 7 % 2 equals 1 because 7 divided by 2 leaves a remainder of 1.
The Question: If Number % 2 == 0, what does that tell you about Number? Is it even or odd? Don’t let the simplicity fool you!
A Little Nudge…
Think about what it means for a number to be perfectly divisible by 2… What’s left over?
The Solution!
Brain check! If Number % 2 == 0, then Number is even. That’s because an even number is perfectly divisible by 2, leaving no remainder.
// Example in JavaScript
function isEven(number) {
return number % 2 === 0;
}
console.log(isEven(4)); // Output: true (Even)
console.log(isEven(7)); // Output: false (Odd)
