How to make use of it:

1. Create a Textarea component to simply accept long paragraphs.

<textarea id="text" rows="5"></textarea>

2. Create a choose component from which you’ll choose the number of sentences per paragraph.

<select id="sentences">
  <option value="2">2</option>
  <option value="4">4</option>
  <option value="6">6</option>
</select>

3. Load the required jQuery JavaScript library on the finish of the doc.

<script src="/path/to/cdn/jquery.slim.min.js"></script>

4. The most important JavaScript (jQuery script) to allow the lengthy paragraph converter.

function paragrphier(){

  let text = $('#text').val();
  let sentences = $("#sentences option:selected" ).val();

  const expectedSentenceCount = sentences;
  let overallCount = 0;
  let sentenceCount = 0;
  let previousIndex = 0;

  const totalFullStops = (text.match(/,/g) || []).length;

  
  $('#sentenceCount').html('Total Number Sentences: '+ totalFullStops);

  let newText = '';

  for(let i = 0; i < text.length; i++){
    let value = text.charAt(i);

    if(sentenceCount == expectedSentenceCount){
      newText += text.substring(previousIndex, i) + '</br></br>';
      previousIndex = i;
      sentenceCount = 0;

      if((totalFullStops - overallCount) < expectedSentenceCount ){
      newText += text.substring(previousIndex, (text.length)) + '</br></br>';
      }
    }

    if(value === '.'){
      sentenceCount += 1;
      overallCount += 1;
    }


  }
  
  
  $('#outputText').html(newText);
  
}

5. Create a convert button on the web page.

<button onclick="paragrphier()">Paragraphy</button>

6. Create an empty container to hold the output.

<div id="outputText">
</div>
