 ```
+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
+```
