## Use Destructuring Assignment with the Rest Operator to Reassign Array Elements
<!-- The article goes here, in GitHub-flavored Markdown. Feel free to add YouTube videos, images, and CodePen/JSBin embeds -->
Remember that the rest operator allows for variable numbers of arguments. In this challenge, you have to get rid of the first two elements of an array.
## Hint 1:
Assign the first two elements to two random variables.
## Hint 2:
Set the remaining part of the array to `...arr`.
=======
## Hint 1
Use destructuring to create the `arr` variable.
```javascript
function removeFirstTwo(list) {
"use strict";
// change code below this line
const [arr] = list; // change this
// change code above this line
return arr;
}
```
## Hint 2
Spread the `list` parameter into `arr`.
```javascript
function removeFirstTwo(list) {
"use strict";
// change code below this line
const [...arr] = list; // change this
// change code above this line
return arr;
}
```
## Hint 3
Exclude the first two elements of the `arr` array with `,,`.
```javascript
function removeFirstTwo(list) {
"use strict";
// change code below this line
const [,,...arr] = list; // change this
// change code above this line
return arr;
}
```
## Spoiler Alert - Solution Ahead!
```javascript
function removeFirstTwo(list) {
"use strict";
// change code below this line
const [a, b, ...arr] = list;
// change code above this line
return arr;
}
```
