Task: Write a JS function to check whether an year is leap.
Leap years are either divisible by 4 but not by 100 or are divisible by 400.
- The input comes as a single number argument.
- The output should be printed to the console. Print yes if the year is leap and no otherwise.
Examples:
Input:
1990
Output:
no
Input:
2000
Output:
yes
Input:
1900
Output:
no

My solution to the task:
function leapYear(input) {
let year = input;
let answer;
if ((year % 4 == 0 && year % 100 != 0) || year % 400 == 0) {
answer = "yes";
} else {
answer = "no";
}
console.log(answer);
}
leapYear(1999);

My solution with ternary operator:
function leapYear(year) {
let leap = (year % 4 == 0 && year % 100 != 0) || (year % 400 == 0);
console.log(leap ? "yes" : "no");
}
leapYear(2000);

2 solutions from me:
function isLeapYear(year) {
return (year % 4 == 0 && year % 100 != 0) || (year % 400 == 0)
}
console.log(isLeapYear(1999));
function checkY(y) {
return ((y % 4 == 0 && y % 100 != 0) || (y % 400 == 0)) ? "yes" : "no";
}
console.log(checkY(2000));
