The readableQuery const

The url Andrew Chalkley uses does not do what is shown on the video. The url given in the documentation looks like this: http://api.wunderground.com/api/${key}/conditions/q/CA/San_Francisco.json - it includes a state. So now the get function requires one more property and also gives the part //const query = process.argv.slice(2).join("").replace(' ', '');// a serious issue. I am stuck with that.

Hi Petar , I had the same problem and fixed it by using:

var state = process.argv.slice(2)[0];
var city = process.argv.slice(3);

var queryString = `https://api.wunderground.com/api/${api.key}/conditions/q/${state}/${city}.json`

and giving the function the two arguments:

weather.get(state,city);

I admit it is not very elegant, maybe someone found a prettier solution ?

With destructuring assignment, you can also do this:

const [,, state, city] = process.argv;

var queryString = `https://api.wunderground.com/api/${api.key}/conditions/q/${state}/${city}.json`;
