Jaswin

While it is true that there is a legit concern for security, especially as the code is executed on the users computers, javaScript come with several advantages that make it quite appealing especially on the client side.
Not only does it play nicely with other programming languages and can be added into any web page irrespective of extension, but it can also be run immediately without having to contact the server and wait for an answer.
Jaswin is a lightweight javascript library that enables you to create user interfaces that take the form of discrete applications, such as checkboxes, windows, buttons,  menus, list view or tree views just to name a few.
Since the library addresses web applications mostly, it is understandable that the program employs an Ajax framework to facilitate the communication between the application and the server. Ajax frameworks are mostly employed to design dynamic web pages on the client side and entail that the data is read and send to the server by Javascript requests.
Thanks to applications such as Jaswin, now you can send HTTP request that includes the application parameters or data in the form of XML or text. The idea behind the app is to make sure you receive the HTTP responses in either plain text or as an XML file. The advantage that stems from this is that the server applications can decode the queries and operations requested more efficiently.
