Answer 1

You can try a splitter like

function split(str) {
  var len = str.length,
    mid = Math.floor(len / 2);

  var left = mid - str.substring(0, mid).lastIndexOf(' '),
    right = str.indexOf(' ', mid) - mid;

  var ind = mid + (left < right ? -left : right);

  return [str.substr(0, ind),
    str2 = str.substr(ind)
  ];
}

var parts = split("123-456 3-5-asldfkjas kdfasdfasd fjas");
snippet.log(parts[0]);
snippet.log(parts[1]);
