Convert Ruby String gsub! to javascript string replace method

Question

I have snip code in Ruby that used gsub! method as below

# handle headings (H1-H6)
text.gsub!(/(<\/h[1-6]>)/i, "\n\\1") # move closing tags to new lines
text.gsub!(/[\s]*<h([1-6]+)[^>]*>[\s]*(.*)[\s]*<\/h[1-6]+>/i) do |s|
  hlevel = $1.to_i

  htext = $2
  htext.gsub!(/<br[\s]*\/?>/i, "\n") # handle <br>s
  htext.gsub!(/<\/?[^>]*>/i, '') # strip tags             
  hlength = 3

  case hlevel
    when 1   # H1, equal below
      htext = "\n" + htext.upcase + "\n" + ('=' * hlength)
    when 2   # H1, dashes below
      htext = "\n" + htext.upcase + "\n" + ('-' * hlength)
    else     # H3-H6, dashes below
      htext = "\n" + htext + "\n" + ('+' * hlength)
  end
  htext
end

Above snip will convert html string to plain text. this process for H(s) tag.

I need to port the snip to javascript that will use replace method Someone can help me, thanks

I think i know what you search for, but would be good to see the point where you need help. Where is your javascript? I mean stackoverflow is to help/support, not for completing issues? — SG 86
