Answer

You can use something like /((\.|\?|\!)\s)|(\?|\!)|(\.$)/g to get the elements. Here is a pseudo breakdown of each capture group:

  1. ((\.|\?|\!)\s): any .,? or ! followed by whitespace.
  2. (\?|\!): any standalone ?or !.
  3. (\.$): any . followed by end-of-line. (this one might be unnecessary depending on the string)

Here is the rough code to get you on track:

console.clear();
var str = 'This is a wordpress plugin. its older version was 2.3.4 and new version is 2.4. But the version 2.4 had a lot of bungs. Can we solve it?';
console.log('"' + str + '"');
console.log('Becomes:');
console.log('"' + str.replace(/((\.|\?|\!)\s)|(\?|\!)|(\.$)/g, ".\n") + '"');

The "real deal" would properly have to replace over several rounds to account for the different symbols:

console.clear();
var str = 'This is a wordpress plugin. its older version was 2.3.4 and new version is 2.4. But the version 2.4 had a lot of bungs. Can we solve it?';
str = str
  //"all"
  //.replace(/((\.|\?|\!)\s)|(\?|\!)|(\.$)/g,".\n")
  //"."
  .replace(/((\.)\s)|(\.$)/g, ".\n")
  //"?"
  .replace(/((\?)\s)|(\?)/g, "?\n")
  //"!"
  .replace(/((\!)\s)|(\!)/g, "!\n")
console.log(str)
