Function toString()

The toString() method is used to convert a function to string. The method converts the function back to the JavaScript source. The converted string includes all aspects of the defined function. <html>     <body>     <script lanuguage="JavaScript">     <!--     function writeText(){          document.write("Some dummy text");     }     var func = writeText.toString();     document.write("The string representation of the writeText");     document.write(" function looks like: " + "<br><br><b>");     document.write(func + "</b>");     -->     </script>     </body>     </html>
