Tell us what’s happening:
Hi,
my code give me a result that looks like the one of the exemple, but i still am stucked with this error :
“18. After you click #sort-btn, #array-container should contain as many div elements as the steps required by the Bubble Sort algorithm to sort the starting array, including the div representing the starting array and a div representing the sorted array.”…
I dont understand, as i have all the divs requested, have my starting array and my sorted array that looks corrects.
thanks for the help. 
Your code so far
