var age = 8;

here is my second file ex3_6.js
document.write("<b>Name:</b> " + string + "<br />");
document.write("<b>Age:</b> " + age + "<br />");
document.write("<b>SSN:</b> " + ssn + "<br />");
document.write("<b>Job Title:</b> " + job_title+"<br />");
ssn="xxx-xx-xxxx";
document.write("<b>Now SSN is:</b> " + ssn , "<br />");
Use your Java skill to do the following:
a. Keep all var statement but declare a string variable say ‘s’ with initial value of an
empty string;
b. Combine all string into one long string so that in the end
of your program you
only have one “document.write(s)” which will produce the same result as the
textbook example.
c. You may use any picture file for the image.
