I have an Integer input that I want to output as 2 digits.
Besides using padStart()
String(month).padStart(2, '0')
My current solution:
`${String(month).length > 1 ? '' : '0'}${month}`
Is there a more elegant/another way to do the same?

What's wrong with `padStart`? – Phil Jul 11 '18 at 05:24

3I'd rather check whether the number is less than 10 than to check whether the String-number's `length` is greater than 1 – CertainPerformance Jul 11 '18 at 05:24

1@Phil I'm using a node that's not supporting `padStart()` yet; so thought of writing one myself instead of using polyfill – Jee Mok Jul 11 '18 at 05:27

great idea @CertainPerformance! – Jee Mok Jul 11 '18 at 05:28

2`('0'+month).substr(-2)` – Jaromanda X Jul 11 '18 at 05:39

or add the polyfill from https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/padStart#Polyfill ... then start using modern javascript :p – Jaromanda X Jul 11 '18 at 05:42
