What is the difference between JQuery and Javascript

What is the difference between JQuery and jQuery UI


jQuery UI is the library built upon JQuery. It is a ready-to-work framework which contains collective set of web elements like
1) Interactive elements
2) Widgets which are generally used
3) Effects
4) Utilities

Instead of creating our own elements like date picker or sortable or auto complete we can make use of this library. It consumes less development time.
jQuery UI provides its own theming and it has its own stylesheets. JQuery UI supports both desktop and mobile. As we mentioned already jQuery has low backward compatibility to IE and so jQuery UI too. jQuery UI is not seeing growing updates.
The latest version of jQuery UI is 1.12.0 and released in 2016.
JQuery UI is jQuery and nothing to compare.
