Suppose we have string like this:
Hello, my\n name is Michael. How can I remove that new line and strip those spaces after that into one inside of string to get this?
Hello, my name is Michael.

Use JavaScript's string. replace() method with a regular expression to remove extra spaces. The dedicated RegEx to match any whitespace character is \s . Expand the whitespace selection from a single space to multiple using the \s+ RegEx.
Using sting split() and join() You can also use the string split() and join() functions to remove multiple spaces from a string.
The metacharacter “\s” matches spaces and + indicates the occurrence of the spaces one or more times, therefore, the regular expression \S+ matches all the space characters (single or multiple). Therefore, to replace multiple spaces with a single space.
To eliminate spaces at the beginning and at the end of the String, use String#trim() method. And then use your mytext. replaceAll("( )+", " ") .
