EN

var checkProps = [ {symbol: 'rwerwe'}, {side: 'Buy'}, {status: 'Hey'} ];
var urlStr = 'localhost:3000/';
var urlParams = [];
checkProps.forEach(function(o) {
  var keys = Object.keys(o);
  keys.map(function(key) {
      urlParams.push(key + '=' + o[key])
  });
});

urlStr += urlParams.join('&');
console.log(urlStr)

const parameters = checkProps.map(item => Object.keys(item).map(key => key + "=" + item[key])[0])
                             .join("&");
const myUrl = `localhost:3000/${parameters}`;

const parameters = checkProps.map(item => Object.entries(item)[0])
                             .map(parameter => parameter.join("="))
                             .join("&");
