Split a string with multiple regular expressions, then flatten the results

multiSplit.js

// var splitResults = multisplit(str, regExp1[, regExp2[, ...[, regExpN]]])
// returns single-leveled array of split results
var multiSplit = function (str) {
  
  var regexps = [].slice.call(arguments).slice(1);
  
  var parts = [str];
  while (regexps.length) {
    parts = parts.map(function(part){ return part.split(regexps[0]); });
    parts = Array.prototype.concat.apply([], parts);
    regexps.shift();
  }
  
  return parts;
  
}
