Course Testimonials
Ramachandran
I have been a web developer some time and so far have mostly focused on developing websites which were HTML and CSS. I had basic training on usage of how to do basic java script development and how to use them in real time applications and websites. But all the older technologies are becoming a thing of the past and users demand faster loading websites without waiting for pages to load. Like say Gmail a single page app/service. That concept pushed me towards learning Ajax and I got introduced to jQuery. In this site I came across this nifty tutorial on Sammy Js which happens to be a very simple framework for loading front end results for single page applications like Gmail with the help of URL calls. I got interested and learnt it and now I can comfortably develop Ajax oriented apps based on the Sammy Js framework.
Henry
I heard of Sammy JS from some of my web developer friends and was very to keen to try it out. It turned out to be a very good tutorial as it explained in detail what is Sammy Js and how we can incorporate it in our existing framework of scripts. Its layer built on jQuery so you need to have basic understanding of jQuery, JSON and Ajax for this course. But well its taken for granted that you are not new to web programming just like me and used to something like this so yeah go ahead and undertake this course not only because the course will train you well but also because of the fact that for modern day web development Sammy Js is a real cool script to pick up and base your work on.
Ramirez
I consider myself a medium level web developer with decent experience in Java and Ajax but I still found this tutorial helpful as it explained all the features of Sammy JS quite in depth. The confusions I had regarding the way I can use this software got solved. So I will highly recommend this course to anyone who has actually heard of Sammy Js and looking for a way to learn this java scripting framework for building Ajax and jQuery oriented websites.
Dorris
I have traditionally been a HTML developer with Java Script understanding and basic skills. When I look at the web world of today I see faster and faster loading websites which is pushing the boundaries of a web surfers expectations from a website. Gradually I started training myself on Ajax and jQuery and JSON and gradually things are getting clear for me. Some where during this learning curve of mine I came across Sammy Js and got inquisitive enough to try it out. So I learnt this java web app development framework and I must say its a real cool script to learn and play around with. You should see some cool apps I have developed with the SammyJs framework. The course did help a lot.
