JavaScript String trimEnd() Method

Quiz

The JavaScript String trimEnd() method is used to remove whitespace characters from the end (right side) of the current string. It returns a new string without modifying the original string. If the end of the string has no whitespace, the new string will be the same as the original string.

To remove whitespace characters from both ends of a string, we can use the trim() method. To remove whitespace characters from only one end of a string, you can use the trimStart() or trimEnd() methods, depending on which end you want to trim.
