Javascript Arguments Preference [closed]

Question

Just a style question.

do you people prefer to pass in variables into a function like

function (a, b) {
    return a + b;
}(1,2);

or 

function (args){
    return args.a + args.b;
}({a:1;b:2});

?

Are there any performance issues between the two?

I'm deciding on standardizing my functions in some way, therefore I'm asking this question.

Answer 1

If it's just a few parameters I would use the first for better readability (documentation).

If there are a lot of parameters, I would use the second one (for example options object).

I don't think there's any major performance difference between the two.
