freeCodeCamp Challenge Guide: Remove Items Using splice()

Remove Items Using splice()


Problem Explanation

The splice() function must be called on the arr array in order to remove 1 or more elements from the center of the array.


Hints

Hint 1

The array arr currently adds up to the value of 27. Simply remove as many elements from arr, so the sum of the remaining elements is 10.

Hint 2

Think about which group of consecutive elements you can remove so that the only elements left sum to 10.
