Javascript is the most popular programming language* and its usage has grown 25% in the past year**. It’s widely used and so it stands to reason that Oracle now released a brand new JavaScript toolkit called Oracle JET (JavaScript Extension Toolkit).

Oracle says “Oracle JET is targeted at intermediate to advanced JavaScript developers working on client-side applications. It’s a collection of open source JavaScript libraries along with a set of Oracle contributed JavaScript libraries that make it as simple and efficient as possible to build applications that consume and interact with Oracle products and services, especially Oracle Cloud services.”

JET is a toolkit bases on JavaScript, CSS3 and HTML5 design and development principles and offers support for ‘Accessibility’ and ‘Internationalization’. It targets JavaScript developers working on client-side web applications.
JET is based on several open source libraries such as JQuery and Knockout and has a highly modular structure with the purpose of allowing you to pick and choose the functionality that suits your needs.

One may argue that Knockout is not the most modern library choice to include in JET, but Oracle did not make this decision lightly. Instead of going for an all-in-one solution like AngularJS, they really aimed at keeping JET modular. So they chose libraries that are tailor made for their specific propose. In case of Knockout this means a lightweight library that excels at providing a declarative two-way data-binding.

So how does OracleJET fit in with the other frameworks like ADF and MAF? The information released at OOW15 focused/differentiated mainly on the target audience and stated that:

· Oracle ADF is for Java developers looking for a more declarative development approach to build web based applications.

· Oracle JET is for intermediate and advance JavaScript developers looking to build web bases applications.

· Oracle MAF is for developers looking for a more declarative development approach to build on-device mobile applications.

Additional comparison data was mainly tech based as stated in the table below showing JET vs ADF and the slide photo depicting the target audience. Read the complete article here.
