JavaScript(JS) JS check if a number is odd or even

In JavaScript, you can check if a number is odd or even by using the modulo operator %. An even number divided by 2 will have a remainder of 0, whereas an odd number divided by 2 will have a remainder of 1. Here's an example:

const num = 5;

if (num % 2 === 0) {
  console.log(`${num} is even.`);
} else {
  console.log(`${num} is odd.`);
}

In the above example, we first create a variable num with the value of 5. We then use the modulo operator % to check if num is even or odd. If num is even (i.e., the remainder of num divided by 2 is 0), we log a message saying that num is even. Otherwise, if num is odd (i.e., the remainder of num divided by 2 is 1), we log a message saying that num is odd.

You can replace the value of the num variable with any other number to check if it is odd or even.
