                   for (let j = 0; i < s.length; j++) {
                      if( i!= j && s[i] == s[j]){
                        repeat =1;

I’ve edited your post for readability. When you enter a code block into the forum, remember to precede it with a line of three backticks and follow it with a line of three backticks to make easier to read. See this post to find the backtick on your keyboard. The “preformatted text” tool in the editor (</>) will also add backticks around text.

I see a few possible problems, but it’s hard to tell which one is causing your current error without you telling us what it is.
