@chezearth/string/lib/_splitRight.js

This is a temporary package until I can open a pull request on the original. string contains methods that aren't included in the vanilla JavaScript string such as escaping html, decoding html entities, stripping tags, etc.

function splitRight(self, sep, maxSplit, limit) {

  if (typeof maxSplit === 'undefined') {
    var maxSplit = -1;
  }
  if (typeof limit === 'undefined') {
    var limit = 0;
  }

  var splitResult = [self];

  for (var i = self.length-1; i >= 0; i--) {

    if (
      splitResult[0].slice(i).indexOf(sep) === 0 &&
      (splitResult.length <= maxSplit || maxSplit === -1)
    ) {
      splitResult.splice(1, 0, splitResult[0].slice(i+sep.length)); // insert
      splitResult[0] = splitResult[0].slice(0, i)
    }
  }

  if (limit >= 0) {
    return splitResult.slice(-limit);
  } else {
    return splitResult.slice(0, -limit);
  }

}

module.exports = splitRight;
