In this
lesson I decided to use a one line if/else statement and since I don’t need anything on the else side I had to “waste” an action somehow is there a better way to do it?
function filteredArray(arr, elem) {
let newArr = [];
// Only change code below this line
for (let i=0;i<arr.length;i++){
arr[i].indexOf(elem) < 0 ? newArr.push(arr[i]): arr=arr;
}
// Only change code above this line
return newArr;
}
console.log(filteredArray([[3, 2, 3], [1, 6, 3], [3, 13, 26], [19, 3, 9]], 3));
