You can try following:

You are using capturing parentheses but you are not using the results of
that capture anywhere so why use them? You are using capturing
parentheses in LIST context so even if there are multiple whitespace
characters you are only capturing ONE.
If you are using the parentheses for grouping then it would be more
efficient to use non-capturing parentheses instead, but grouping only
makes sense if you have a GROUP of characters to match, but you only
have ONE.
The use of the /g option is superfluous because the pattern is anchored
to the beginning of the string and there is only ONE beginning of string
in any string.
