Below example illustrate the Remainder assignment(%=) Operator in JavaScript:

Example 1: The following example demonstrates if the given number is divisible by 4 or if it’s an even or odd number.

Javascript

<script>
    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);
    }
</script>

Output:

true
true
false

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

Javascript

<script>
    let gfg = 3;

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

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

    console.log((gfg %= "world"));
</script>

Output:
