Create a self-submitting form page that accepts the user’s first and last name in 2 text boxes. On submission, your script should replace all instances of the letter “s” with the number “5”, determines the location of the first “e” (if one exists), and evaluates whether the last 3 characters of the last name are “son”. The modified text should be displayed on the page after submission with the first “e” underlined and the last 3 characters in italics ONLY if they are “son”.
