I am making a weather app using HTML, CSS, JS, so i took api from https://openweathermap.org/current and used that in my code but i didn’t get the proper/expected result in the browser console.
I don’t know how to access the objects from the result. I need to take/access weather.main, main.temp, main.humidity, wind.speed

code:

async function getData(){
    let response = await fetch(weatherAPI);
    let data = await response.json();
    return data;
}

console.log(getData());

result:

Promise {<pending>}
[[Prototype]]
: 
Promise
[[PromiseState]]
: 
"fulfilled"
[[PromiseResult]]
: 
Object
base
: 
"stations"
clouds
: 
{all: 20}
cod

coord
: 
{lon: -0.1257, lat: 51.5085}
dt

main
: 
{temp: 15.6, feels_like: 14.86, temp_min: 14.72, temp_max: 17.25, pressure: 1026, …}
name

"London"
sys
: 
{type: 2, id: 2075535, country: 'GB', sunrise: 1684469018, sunset: 1684525832}

visibility
:

weather
:

wind
: 
{speed: 3.6, deg: 50}

expected result:

{

    "lon": 10.99,
    "lat": 44.34
  },
  "weather": [
    {
      "id": 501,

  },
  "timezone": 7200,

  1. You aren’t waiting for the promise to be fulfilled.

    let data = await getData() // data will hold your response
    
    OR
    
    async function logData() {
      let data = await getData();
      console.log(data);
    }
    
    logData(); // console logs your expected result

  2. The reason is that you are not waiting for the promise fulfilled. Mainly a promise has 3 statutes. (pending, fulfilled and rejected.)

    • pending – Before resolving the promise.
    • fulfilled – after resolving the promise successfully.
    • rejected – promise resolving failed.

    when you call the getData() method without async/await or .then(), it will print the pending states result instead of the expected result. If you want to print actual results you have to put .then() or async/await.

    getData().then((res)=>{
    
      console.log(res)
    
    })
    

    or

    (async ()=>{
    
      const response = await getData();
      console.log(response)
    
    })
