What are the contents of the array arr after the following code executes?

let arr = [];
for (let i = 1; i <= 8; i++) {
    arr.push(10 * i);   //   0   1   2   3   4   5   6   7
}                       // [10, 20, 30, 40, 50, 60, 70, 80]
for (let i = 0; i < arr.length; i++) {
  arr.splice(i, 1);
}


`[]` `[10, 20, 30, 40, 50, 60, 70, 80]` `[20, 40, 60, 80]` `[10, 20, 30, 40]` `other`
