Javascript date - Leading 0 for days and months where applicable

Question

Is there a clean way of adding a 0 in front of the day or month when the day or month is less than 10:

var myDate = new Date();
var prettyDate =(myDate.getFu         


        

Answer 1

The easiest way to do this is to prepend a zero and then use .slice(-2). With this function you always return the last 2 characters of a string.

var month = 8;

var monthWithLeadingZeros = ('0' + month).slice(-2);
