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

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

You can replace matched fragment with for example: `$1#` (or other char not
occuring in text, instead of `#`), and then split it with `#`

solution.
