Splitting paragraph into sentences

Question

I'm using the following Python code (which I found online a while ago) to split paragraphs into sentences.

def splitParagraphIntoSentences(paragraph):
  import re
  sentenceEnders = re.compile(r"""
      # Split sentences on whitespace between them.
      (?:               # Group for two positive lookbehinds.
        (?<=[.!?])      # Either an end of sentence punct,
      | (?<=[.!?]['"])  # or end of sentence punct and quote.
      )                 # End group of two positive lookbehinds.
      (?<!  Mr\.   )    # Don't end sentence on "Mr."
      (?<!  Mrs\.  )    # Don't end sentence on "Mrs."
      (?<!  Jr\.   )    # Don't end sentence on "Jr."
      (?<!  Dr\.   )    # Don't end sentence on "Dr."
      (?<!  Prof\. )    # Don't end sentence on "Prof."
      (?<!  Sr\.   )    # Don't end sentence on "Sr."."
    \s+               # Split on whitespace between sentences.
    """, 
    re.IGNORECASE | re.VERBOSE)
  sentenceList = sentenceEnders.split(paragraph)
  return sentenceList

I works just fine for my purpose, but now I need the exact same regex in Javascript (to make sure that the outputs are consistent) and I'm struggling to translate this Python regex into one compatible with Javascript.

Answer 1

It is not regex for direct split, but kind of workaround:

(?!Mrs?\.|Jr\.|Dr\.|Sr\.|Prof\.)(\b\S+[.?!]["']?)\s

DEMO

You can replace matched fragment with for example: $1# (or other char not occuring in text, instead of #), and then split it with # DEMO. However it is not too elegant solution.
