## Examples

```js
// ❌
const absolute = value < 0 ? -value : value;

// ❌
const absolute = value <= 0 ? 0 - value : value;

// ❌
const absolute = value > 0 ? value : -value;

// ✅
const absolute = Math.abs(value);
```

```js
// ❌
if (number > MAXIMUM || number < -MAXIMUM) {
}

// ✅
if (Math.abs(number) > MAXIMUM) {
}
```
