Use `Math.abs()` to extend logic to negative numbers, check using the modulo (`%`) operator. Checks whether number is odd or even using the modulo (`%`) operator.
Return `true` if the number is even, `false` if the number is odd. Returns `true` if the number is even, `false` if the number is odd.
```js ```js
const isEven = num => Math.abs(num) % 2 === 0; const isEven = num => num % 2 === 0;
// isEven(3) -> false // isEven(3) -> false
``` ```
