Changing the section on using commas to skip array elements, so as to make it more explicit that the skipping is possible for the elements in the middle of the array as well.
The code sample and smart-heading give the impression that only the first elements can be skipped.

Unwanted elements of the array can also be thrown away via an extra comma:
```js run
*!*
// first and second elements are not needed
let [, , title] = ["Julius", "Caesar", "Consul", "of the Roman Republic"];
// second and forth elements are not needed
let [firstName, , title] = ["Julius", "Caesar", "Consul", "of the Roman Republic"];
*/!*
alert( title ); // Consul
```
In the code above, although the first and second elements of the array are skipped, the third one is assigned to `title`, and the rest are also skipped.
