javascript - 如何以正确的方式在 JavaScript 中编写月份

Question

到目前为止，我已经实现了这个功能，但它看起来又长又难看。有没有办法动态生成月份或其他方法。

为了更好地理解，请参阅这个 fiddle http://jsfiddle.net/Yq3DW/67/

 function formatMonth(d) {
        switch (d) {
        case 0:
            return "Jan";
            break;
        case 1:
            return "Feb";
            break;
        case 2:
            return "Mar";
            break;
        case 3:
            return "Apr";
            break;
        case 4:
            return "May";
            break;
        case 5:
            return "Jun";
            break;
        case 6:
            return "jul";
            break;
        case 7:
            return "Aug";
            break;
        case 8:
            return "Sep";
            break;
        case 9:
            return "Oct";
            break;
        case 10:
            return "Nov";
            break;
        case 11:
            return "Dec";
        default:
            return "Jan"
        }
    }


function (d) {
return formatMonth(d);
}

var formatMonth = function(i) {
  return ["Jan", "Feb", "Mar", "Jul", "Jun", "Aug", "Sep", "Oct", "Nov", "Dec"][i];
};
console.log(1, formatMonth(1));
console.log(0, formatMonth(0));
