Learn Basic Algorithmic Thinking by Building a Number Sorter - Step 15

Tell us what’s happening:

the hint says " Your inner for loop should iterate through every element in the array except the last one." but i don’t know how to write it … i tried this “array[i-1]” but it didn’t work …
please help me to fix it, thanks

Your code so far

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


The challenge seed code and/or your solution exceeded the maximum length we can port over from the challenge.

You will need to take an additional step here so the code you wrote presents in an easy to read format.

Please copy/paste all the editor code showing in the challenge from where you just linked.

Replace these two sentences with your copied code.
Please leave the ``` line above and the ``` line below,
because they allow your code to properly format in the post.

how do you solve it?

Hi @arifsyah1018
This thread is a little old by now. Could you post a new thread explaining what kind of problems you are having to solve it?

My problem is the same as his

If you post in a new thread, I am quite sure we can figure out how to help you.
Thank you.
