After looking for the perfect solution using regex and other implementations. I decided to right my own. It is not perfect however worked nice for my case, maybe it does not work properly when you have all your text in Upper case.

function breakTextNicely(text, limit, breakpoints) {

  var parts = text.split(' ');
  var lines = [];
  text = parts[0];
  parts.shift();

  while (parts.length > 0) {
    var newText = `${text} ${parts[0]}`;

    if (newText.length > limit) {
      lines.push(`${text}\n`);
      breakpoints--;

      if (breakpoints === 0) {
        lines.push(parts.join(' '));
        break;
      } else {
      	text = parts[0];
	  }
    } else {
      text = newText;
    }
	  parts.shift();
  }

  if (lines.length === 0) {
    return text;
  } else {
    return lines.join('');
  }
}

var mytext = 'this is my long text that you can break into multiple line sizes';
console.log( breakTextNicely(mytext, 20, 3) );
