Just for a laugh do it the long nasty way....:
(NOTE: ive not used this, and i would not advise using this.!)

function pad(str, new_length) {
    ('00000000000000000000000000000000000000000000000000' + str).
    substr((50 + str.toString().length) - new_length, new_length)
}

Try following, which will convert convert single and double digit numbers to 3 digit numbers by prefixing zeros.

var base_number = 2;
var zero_prefixed_string = ("000" + base_number).slice(-3);

By adding 100 to the number, then run a substring function from index 1 to the last position in right.

var dt = new Date();
var month = (100 + dt.getMonth()+1).toString().substr(1, 2);
var day = (100 + dt.getDate()).toString().substr(1, 2);

console.log(month,day);

you will got this result from the date of 2020-11-3

11,03

I hope the answer is useful
