## Problem Statement

given a number, write a JavaScript program with a function that takes the number as argument, and prints if the given number is even or odd

## Solution

an even number leaves a remainder of 0 when divided by 2, and the odd number leaves a reminder of 1 when divided by 2

we can use arithmetic modulus operator to find the remainder of the division of given number by 2

## Programs

1. check if value in `num`

is even or odd number using if-else statement

```
var num = 10;
if (num % 2 == 0) {
console.log('even number');
} else {
console.log('odd number');
}
```
