It would be cool if a function like:

function joinObjs()

{

var newObj = {};

for(var i = 0;i < arguments.length; i++)

{

if(typeof(arguments[i]) == "object")

{

for(key in arguments[i])

{

newObj[key] = arguments[i][key];

}

}

}

return newObj;

}

was added to the core of jQuery. I find myself needing to join objects all the time, and it would be useful if it was added to jQuery.
