2 ways of binding data to JSP

There are 2 ways of binding data to the JSP.

1. Using JSTL. JSTL can help to retrieve the data from the server and populate it in the JSP. But the issue is that we can’t dynamically add the html elements inside the JSP.
2. Using Handlebars. We can get the data from ajax calls inside the JS, then add it to handlebar then append the handlebar to JSP. This way allows us to add multiple elements and make the page dynamic. Remember to compile the handlebar inside the JS
