1. Напишите функцию разбора query-строки в набор параметров.

gistfile1.js

var query_to_object = function(url) {
  var param, params, query, result, _i, _len;
  if (url == null) {
    url = 'http://moto1.englearn.org/index.php?route=product/product==&path=59&product_id=50';
  }
  query = url.split('?')[1];
  result = {};
  if (query != null) {
    params = query.split('&');
    for (_i = 0, _len = params.length; _i < _len; _i++) {
      param = params[_i];
      param = param.split('=');
      result[param.splice(0, 1)] = param.join('=');
    }
  }
  return result;
};

gistfile2.coffee

query_to_object = (url = 'http://moto1.englearn.org/index.php?route=product/product==&path=59&product_id=50' ) ->
  query  = url.split('?')[1]
  result = {} 
  if query?
    params = query.split('&')
    for param in params
      param = param.split('=')
      result[param.splice(0,1)] = param.join('=')
  result
