// Define variable year and initialize value
{
if ((year % 4 == 0 && year % 100 != 0) || year % 400 == 0) {
// three conditions to find leap year
// The number which is divided by 4 or 400 is a leap year.
// The number that divided by 100 is not zero is leap year
console.log(year + " is leap year");
} else {
console.log(year + " is not leap year");
}
}
```
