JavaScript can now be used end-to-end from backend to frontend applications. JaggeryJS is a framework that allows developers to write full web applications using only JavaScript. It provides APIs to access databases, call web services, and integrate with WSO2 products. JaggeryJS applications can be developed similarly to PHP/JSP applications, removing the need to compile or build code. Developers are now able to build rich web applications using JavaScript and common libraries across the full stack.
