Tell us what’s happening:

I dont know what’s wrong with my nested for loop. The system won’t let me pass.

const bubbleSort = (array) => {
for (let i = 0; i < array.length - 1; i++) {
for (let j = 0; j < array.length - i - 1; j++) {

  if (array[j] > array[j + 1]) { 
    
    
    
    let temp = array[j];
    array[j] = array[j + 1];
    array[j + 1] = temp;

    
  }
}

}

};

You need to:

  • reset,
  • leave the outer for loop untouched.
  • and try again on your inner loop without the swap code first.
