The modulo operator (%) in JavaScript lets us get the remainder when we divide one number by the other.

In this article, we’ll look at how to use modulo operator (%) in JavaScript.

### How to use modulo operator (%) in JavaScript?

We can use the modulo operator to get the remainder of the left operand divided by the right one.

For instance, we write:

``````const numFn = (num) => {
if (num % 14 === 0) {
console.log('foobar')
return
} else if (num % 7 === 0) {
console.log('foo')
return
} else if (num % 2 === 0) {
console.log('bar')
return
}
console.log('NUMBER')
}
``````

We check if `num` can be divided by 14 evenly with `num % 14 === 0`.

If it is, we log `'foobar'`.

Similarly, we do the same checks when dividing `num` by 7 and 2 and log different values.

Otherwise, we log `'NUMBER'` if none of the conditions are `true`.

### Conclusion

We can use the modulo operator to get the remainder of the left operand divided by the right one.
