let num = 16;

// Test if its divisible by 4
if (num % 4 == 0) {
    console.log(true);
}
// Test for even number
if (num % 2 == 0) {
    console.log(true);
} else {
    console.log(false);
}

// Test for odd number
if (!(num % 2 == 0)) {
    console.log(true);
} else {
    console.log(false);
};

Output:

true
true
false

Example 2: The following example demonstrates if the given number is divisible by 2, 0, and world.

let gfg = 3;

console.log((gfg %= 2));

console.log((gfg %= 0));

console.log((gfg %= "world"));
