Tell us what’s happening:
What’s the difference between ‘newArr = newArr.push([…arr]);’ and ‘newArr.push([…arr]);’ ?
Why the first one does not work?
Your code so far
function copyMachine(arr, num) {
let newArr = [];
while (num >= 1) {
// change code below this line
newArr = newArr.push([...arr]);
// change code above this line
num--;
}
return newArr;
}
// change code here to test different cases:
console.log(copyMachine([true, false, true], 2));
