JavaScript Trim Function

You have a Trim functionality on the server side, but what about at client side? Do we have some thing like Trim mechanism for client side scripts?
 
I guess, there is nothing like that... but I found a way to trim the given string.
 
// Replaces the trailing and leading spaces of a given string
function trim(str)
{
    return str.replace(/^\s*|\s*$/g,"");
}
 
The above function returns the string after trimming. I'm posting this here, so that I can recollect as and when I want, instead of googling..
 
What do you say?

Is Architecture = Design of the application

Image
Today morning, I’ve attended an interview with one of the prestigious companies of the world. It doesn’t matter what company is that, but all that matters is the significant means of the questions and the replies by me. I can’t post the entire dialogue questions here, but what I can point here is the gist of the interview. The position is for an architect, who would be working extensively for various stages of the project and should also play the managerial role. Isn’t it asking too much for a given role? Well, in Indian companies, there is no real means of Architect. He is just like any other Manager, but doing the technology stuff as well.
