ES6 - Destructuring via rest elements

JavaScript
1

Tell us what’s happening:

I got it, but the removeFirstTwo([1, 2, 3, 4, 5]) should return [3, 4, 5], and I shouldn’t modify the original array. I need assistance on approaching this.

Your code so far

function removeFirstTwo(list) {
  return list;
}

const [a, b, ...arr] = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
const sourceWithoutFirstTwo = removeFirstTwo(a, b);

so obviously you have to use destructuring assignment for this so have you tried to understand this example as a first step?

const [a, b, ...arr] = [1, 2, 3, 4, 5, 7];
console.log(a, b);
console.log(arr);

What do you think the 2nd log statement does?

3

It prints the arr, the rest of the array.

4

so it prints out an array? And that array is minus the first 2 values?
(Hint Hint)

5

Yes, it prints the array minus the first 2 values. I’m not having trouble with that. I’m having trouble with getting the whole array minus the first two values, and minus the last values.

6

I’m trying to be heavy-handed with the hints here.
The arr is the array minus the first 2 values.

And the objective of this exercise is ??? (double triple hint)

7

Is to print the value of arr.

8

so are you still confused as to how to return an array with all the values except the first 2?
(hint: refer to that example again?)
