Breaking a line while concatenating enhances the readability of the code

Why does the array add a line break between the second to last and last elements when I print it into the debug console after performing this function?

function addToList(URL)
{
    GetWebExceptions(); //defines GExceptionList
    GExceptionList = GExceptionList.concat(URL);
}

For example, it looks like this:

Array: youtube.com,google.com,wikipedia.org
,4chan.org

Additionally, when looping through all the elements with another function an 'undefined' element is found after the one with the line break...

The reason behind this issue is likely due to the addition of '\n' character to your array. To resolve this, try initializing a new array and pushing some strings into it. Then include the '\n' character to see if you encounter the same effect as previously described.
