Javascript change getHours to 2 digit [duplicate]

Question

If the hour is less than 10 hours the hours are usually placed in single digit form.

var currentHours = currentTime.getHours ( ); 

Is the following the only best way to get the hours to display as 09 instead of 9?

if (currentHours < 10)  currentHours = '0'+currentHours; 

Answer 1

Your's method is good. Also take a note of it

var date = new Date(); currentHours = date.getHours(); currentHours = ("0" + currentHours).slice(-2); 

Answer 2

You can do this using below code,

create function,

function addZeroBefore(n) {   return (n < 10 ? '0' : '') + n; } 

and then use it as below,

c = addZeroBefore(deg);
