how to english paragraph matching in javascript

var text = "If he's restin', I'll wake him up! (Shouts at the cage.) 'Ello, Mister Polly Parrot! (Owner hits the cage.) There, he moved!!!\r\n\r\nNorth Korea is accusing the U.S. government of being behind the making of the movie \"The Interview.\"\r\n\r\nAnd, in a dispatch on state media, the totalitarian regime warns the United States that U.S. \"citadels\" will be attacked, dwarfing the attack on Sony that led to the cancellation of the film's release.\r\n\r\nWhile steadfastly denying involvement in the hack, North Korea accused U.S. President Barack Obama of calling for \"symmetric counteraction.\"\r\n\r\n\"The DPRK has already launched the toughest counteraction. Nothing is more serious miscalculation than guessing that just a single movie production company is the target of this counteraction.

var splitSentences = function() {

  var pattern = /(.+?([A-Z].)[\.|\?](?:['")\\\s]?)+?\s?)/igm, match;
  var ol = document.getElementById( "result" );
  while( ( match = pattern.exec( text )) != null ) {
    if( match.index === pattern.lastIndex ) {
      pattern.lastIndex++;
    }
    var li = document.createElement( "li" );
    li.appendChild( document.createTextNode( match[0] ) );
    ol.appendChild( li );
    console.log( match[0] );
  }

}();

Here is what the above code is Doing:
1. It’s creating a variable called text that contains a string of text.
2. It’s creating a function called splitSentences that does the following:
a. It creates a variable called pattern that contains a regular expression.
b. It creates a variable called ol that contains a reference to the element with the id of result.
c. It creates a while loop that does the following:
i. It creates a variable called match that contains the result of the regular expression being executed on the text variable.
ii. It creates an if statement that does the following:
1. It checks to see if the index of the match variable is equal to the lastIndex of the pattern variable.
2. If it is, it increments the lastIndex of the pattern variable by 1.
iii. It creates a variable called li that contains a reference to a new list item element.
iv. It appends a text node to the li variable that contains the first match of the match variable.
v. It appends the li variable to the ol variable.
vi. It logs the first match of the match variable to the console.
3. It executes the splitSentences function.
