How to transform this Regex to not use Lookbehind?

Question

I need to capture all lines starting with the # character in JavaScript. I tried using something like the following regex, but it turns out that JavaScript doesn't support positive lookbehind assertion (?<=).

/(?<=\n)\#[^\n]*/g

How can I transform this regular expression into something supported by JavaScript?

/^ *#(.*)$/m

And capture match[1] for text after #
