Use Destructuring Assignment with the Rest Operator to Reassign Array Elements |
Use Destructuring Assignment with the Rest Operator to Reassign Array Elements
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.
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
.
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 ,,
.
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!
function removeFirstTwo(list) {
"use strict";
// change code below this line
const [a, b, ...arr] = list;
// change code above this line
return arr;
}
