Hi,

I've learned javascript at school but since I'm working with it and study about it every day, I've found very particular aspect of javascript that I didn't know about. Which at first, was very hard to understand for me and finally, I found it very usefull and easy to implement. And in the final, it gives to my code some kind of "beauty".

An example I've once seen:

function getter( input )
{
    result = {
        foo1 : 'bar1',
        foo2 : 'bar2',
        foo3 : 'bar3'
    }[input] || input || "default";

    return result;
}

Do you guys have other examples of particular use you make of Javascript ?

Thank you

PS: I use the term particular use because it might be unusual for any Javascript beginner. I believe this question is most likely to belong to the community wiki.
