Remove all non alphabetic chars from string in Javascript
To remove all non-alphanumeric characters from a string, call the replace() method, passing it a regular expression that matches all non-alphanumeric characters as the first parameter and an empty string as the second. The replace method returns a new string with all matches replaced.
