How to match values into separate optional groups with a regex based on character?

by

3 examples of input:

"13-4h50m2s"
"13-4h2s"
"13-50m"

Preferred code:

const [hours = 0, minutes = 0, seconds = 0] = input.match(some_regexp)

Wanted output {hours,minutes,seconds} for the 3 examples:

{hours: 4, minutes: 50, seconds: 2}
{hours: 4, minutes: 0,  seconds: 2}
{hours: 0, minutes: 50, seconds: 0}

Regex I’ve tried: /(\d+)?[a-z](\d+)?[a-z]?(\d+)?[a-z]?/. But then the second example doesn’t work.

EDIT

Actually, input can be expected to be sorted in the right order (h,m,s).
And it doesn’t matter if the values are stored as strings or numbers.

  22. When someone writes an paragraph he/she retains the image of a user in his/her brain that how a user can understand it.
    Therefore that’s why this piece of writing is perfect.
    Thanks!

  24. Awesome blog! Is your theme custom made or did you download it
    from somewhere? A design like yours with
    a few simple tweeks would really make my blog stand out. Please let me know where
    you got your theme. Many thanks
