Oracle JET is used by JavaScript developers working on client-side applications. This collection of open-source JavaScript libraries, along with a set of Oracle-contributed JavaScript libraries, helps developers build applications that interact with Oracle products and services (especially Oracle Cloud services).

Oracle University now offers the Oracle JavaScript Extension Toolkit (JET) MOOC, a focused, interactive digital learning experience that spans three weeks.

You will learn about JET, a modular JavaScript toolkit that provides the user interface layer of enterprise web and mobile applications. Client-side JavaScript developers, web application developers, and web application designers can all benefit from taking the Oracle JET MOOC, which shows you how to use JET to plan and build applications.

Learn development best practices when working with JET, while developing a solid understanding of how JET is used to extend, interact with, and consume Oracle’s Cloud Services or any Web Service of your own.


Take a MOOC to Learn JET

Compared with more traditional courses, Massive Open Online Courses (MOOCs) offer several advantages. They are less expensive than other types of courses and require no travel, they’re taught by experts, and training is divided into short modules, making it easier to retain what you’ve learned.
