To convert an array to a string without commas, call the join() method on the array, passing it an empty string as a parameter - arr. join('') . The join method returns a string containing all array elements joined by the provided separator. Copied!
join() The join() method creates and returns a new string by concatenating all of the elements in an array (or an array-like object), separated by commas or a specified separator string. If the array has only one item, then that item will be returned without using the separator.
How it works: First, split the title string by the space into an array by using the split() string method. Second, concatenate all elements in the result array into a string by using the join() method. Third, convert the result string to lower case by using the toLowerCase() method.
To convert an array to a string with spaces, call the join() method on the array, passing it a string containing a space as a parameter - arr. join(' ') . The join method returns a string with all array elements joined by the provided separator.
Sure - just pass an empty string:
