what is a downside of interpreted language?

Interpreted languages would not be able to identify certain errors until code is actually run and tested. In a large application, it is very time consuming to manually test every scenario, or to write and maintain additional code that tests of every scenario, whenever code is changed. For example, in a compiled language if a method named GetUser is renamed to GetEmployee as part of some code updates, any reference to GetUser throughout the rest of the application will cause an error during compilation, making it easy to identify and fix.

Why was JQuery needed, if javascript existed?

jQuery is a lightweight, "write less, do more", JavaScript library. The purpose of jQuery is to make it much easier to use JavaScript on your website. jQuery takes a lot of common tasks that require many lines of JavaScript code to accomplish, and wraps them into methods that you can call with a single line of code. Jquery simplifies a lot of the complicated things from JavaScript, like AJAX calls and DOM manipulation

What is the prototype mechanism?

the prototype chain is a linked list where instead of adding more to an object you can point to a function, and still refer to it as if it were a member.
