Remove Items Using splice()
- The
splice()
function must be called on thearr
array in order to remove 1 or more elements from the center of the array. - The array
arr
currently adds up to the value of 16. Simply remove as many variables neccessary to return 10.
Solution:
function sumOfTen(arr) {
// change code below this line
arr.splice(1,2);
// change code above this line
return arr.reduce((a, b) => a + b);
}
// do not change code below this line
console.log(sumOfTen([2, 5, 1, 5, 2, 1]));
