An arrow function does not have its own `arguments` object. For example, if you do not know the number of arguments passed to a function, instead of using `arguments` you can use the `rest` operator:
```javascript
const myFunc = (...n) => {
console.log('The first argument is', n[0]);
}
myFunc(10,20,30,40,40); // output: The first argument is 10
```
