Error handling in axios request

Now aside from the success handler we used in the previous example, we can also add a call to catch, to let us catch all of the errors that might occur. We'll to get the error object as the one-and-only argument; then we can do something with that error object:

axios.get(geocodeUrl).then((response) => { console.log(response.data);});catch((e) => {});

Inside the function, we'll kick things off, using console.log to print the error argument:

}).catch((e) => { console.log(e)});

var encodedAddress = encodeURIComponent(argv.address);var geocodeUrl = `https://mapsgoogleapis.com/maps/api/geocode/json?address=${encodedAddress}`;axios.get(geocodeUrl).then((response) ...
