I'm sorry, Rahul. I may have misunderstood the reason behind your post, as I have heard similar requests in my time as a front-end developer.
However, seeing that the site in your signature does potentially show sensitive information, the best thing I can recommend is to not send any more sensitive information to the browser than what is absolutely needed. Make sure you have good security on the pages this information is on. I don't know if that helps, but I only thought of it as I was walkin to my car.
