Convert dash-separated string to camelCase?

Question

For example suppose I always have a string that is delimited by \"-\". Is there a way to transform

to

itIsAGreatDayToday

See http://jsfiddle.net/54ZcM/

function camelCase(string) {
    return string.toLowerCase().replace(/(\-[a-zA-Z])/g, function($1) {
        return $1.toUpperCase().replace('-','');
    })
}

alert(camelCase('fOo-BarBA-fo'));
