Question

How can we retrieve an API response using Fetch, manipulate it with JSON.stringify(), and what are the next steps in

After countless attempts, I still can't figure out what's missing here.

I'm utilizing fetch to retrieve data from Mapbox:

var response = fetch(myURL)
.then(response => response.json())
.then(data => console.log(JSON.stringify(data)))

Despite successfully logging the fetched data in the console, I'm struggling to manipulate it into a usable format. Specifically, I just need the latitude and longitude coordinates, but all my efforts have been fruitless. I've attempted storing the stringified data in an array, crafting functions to assign it to variables, and yet nothing seems to work.

It feels like there's something glaringly obvious that I'm overlooking. Any guidance would be greatly appreciated.

Below is a snippet of what gets printed to the console log:

data is represented as an object. If you are looking to extract the lat/lng information within the coordinates array, you can achieve this by following these steps.

const data={type:"FeatureCollection",query:["1600","pennsylvania","avenue","washington","dc"],features:[{id:"address.1048737153875776",type:"Feature",place_type:["address"],relevance:.90963,properties:{accuracy:"rooftop"},text:"Pennsylvania Avenue Southeast",place_name:"1600 Pennsylvania Avenue Southeast, Washington, District of Columbia 20003, United States",matching_place_name:"1600 Pennsylvania Avenue Southeast, Washington, DC 20003, United States",center:[-76.982015,38.879235],geometry:{type:"Point",coordinates:[-76.982015,38.879235]},address:"1600",context:[{id:"neighborhood.2918372884011750",text:"Capitol Hill"},{id:"postcode.12587193810898840",text:"20003"},{id:"place.2915387490246050",wikidata:"Q61",text:"Washington"},{id:"region.14064402149979320",short_code:"US-DC",wikidata:"Q3551781",text:"District of Columbia"},{id:"country.14135384517372290",wikidata:"Q30",short_code:"us",text:"United States"}]}]};

// Extract the `coordinates` property from the first element in the `features` array
// and then destructure the lat/lng values from it.
const { coordinates } = data.features[0].geometry;
const [lat, lng] = coordinates;

console.log(lat, lng);

When working with response.json() in JavaScript, you can handle the data in various ways. For example, you could log it to the console as shown below. However, you also have the option to store it in a database using an ajax call or present it in a HTML table for better visualization.

const response = fetch(myURL)
    .then(response => {
        const responseObject = response.json();
        const features = responseObject.features;        
        for (let i = 0; i < features.length; i++) {
            const coords = responseObject.features[i].geometry.coordinates;
            console.log(`${features.id} Latitude = ${coords[0]} Longitude = ${coords[1]}`);
        }
    });
