Nodejs String Reverse reverse()

Method Source Code

//Just like you can add methods to your own constructor, you can also add methods and properties to built in classes in JavaScript like Arrays and Objects.

//Add a reverse method to the String 'class' so that every instance of String can call reverse and reverse itself.
  
  //code here//w ww.  j a v a2  s .com
