Basic Data Structures - Remove Items Using splice()

Programming
1

Tell us what’s happening:

Weirdest thing is happening. When I’m logging the result of arr, it’s completely ignoring splice..

 arr.splice(1,3)
// logs [2,1] - the last two elements.

When I use the same code and assign the value to a new variable I get the correct result.

 let newArr = arr.splice(1,3)
// logs [4,5,1]

Is this an extension issue, have others seen this before?

Note regardles of whether I delete the line let newArr, I still do not get the correct result in arr…

Your code so far

const arr = [2, 4, 5, 1, 7, 5, 2, 1];
// Only change code below this line
let newArr = arr.splice(1,3)
arr.splice(1,3)
// Only change code above this line
console.log(arr);
console.log(newArr)


/*
.splice(index, numberOfItemsToDelete)
*/

The splice is not being ignored at all. You are removing elements at index 1, 2, and 3

It must be a local issue… I’m sure the code splice(1,3) is correct?

Your screenshot shows that you removed the elements 4, 5, 1 from arr.

splice(1, 3) does not meet the requirements of the assignment, no. You are removing three elements, but the remaining elements do not sum to 10.

it’s doing what you wrote, it has removed three elements starting at index 1

notice, that the 4 5 and 1 are not there anymore

Okay, I see… Apologies for the confusion. I understand now!
