@ -85,9 +85,15 @@ An arrow function does not have its own `arguments` object. For example, if you
const myFunc = (...n) => { const myFunc = (...n) => {
console.log('The first argument is', n[0]); console.log('The first argument is', n[0]);
} }
myFunc(10,20,30,40,40); // output: The first argument is 10 myFunc(10,20,30,40,40); // output: The first argument is 10
``` ```
Because of this, an arrow function cannot be used as a constructor, hence there's no need for a `prototype` property.
```javascript
(() => {}).hasOwnProperty('prototype'); // false
```
