Combines functions into single chain. Similar to lodash's _.compose, but updates the first argument to the return value of the previous function.

compose()

function compose() {
  var functions = arguments;
  return function() {
    for (var n=0; n<functions.length; n++) {
      var result = functions[n].apply(functions[n], arguments);
      if (result === false) {
        return false;
      }
      arguments[0] = result;
    }
    return arguments[0];
  }
}
