            response.on('data', function(data) { // Read the data
                json += data;
            });

            response.on('end', () => { // node http on end function and callback, Parse the data
                if ( !JSON.parse(json).response.error && !JSON.parse(json).response.results ) { // if not city not found or search results page
                    let jsonParsed = JSON.parse(json);
                    let weatherInfo = createCurrentWeatherObject(jsonParsed);
                    print.printMessageToConsole(weatherInfo) // print to console
