// example using async/await

const user = async () => {
  	// you must have use async keyword before use await
	const data = await fetch("https://randomuser.me/api/?results=1");

}

what is an async function

Comment

// Old School Javascript Invoke
(async function() {
	await someAsyncFunction();
})();

//New ES6 Javascript Invoke
(async () => {
	await someAsyncFunction();
})();

//Example (async & await)
function delayResult() {
 return new Promise(resolve => {
   setTimeout(() => {
     resolve(‘Done’);
   }, 5000)
 })
}
async function getResult() {
 let result = await delayResult();
 return result;
}
getResult();

//New Example 
const data = async ()  => {
  const got = await fetch('https://jsonplaceholder.typicode.com/todos/1');
  
  console.log(await got.json())
}

data();

Define an async function

Comment

const yourAsyncFunction = async () => {
    // do something asynchronously and return a promise
    return result;
  }
  
anArray.forEach(async item => {
   // do something asynchronously for each item in 'anArray'
   // one could also use .map here to return an array of promises to use with 'Promise.all()'
 });
 
server.getPeople().then(async people => {
  people.forEach(person => {
    // do something asynchronously for each person
  });
});

async await

Comment

// ASYNC will always returns promises
// NOTE : AWAIT should be kept only inside ASYNC function
// AWAIT can't be used in regular function
/* TIPS : Js is single threaded & synchronous in nature BUT, we can
          make it as asyncronous by using (ASYNC/AWAIT)*/

//(Example 1 : fetching Random Image)
async function RandomImage(){  //remember async and await is powerful for async operations, always await should be inside of async only.

  try {
    const raw_response = await fetch("https://www.themealdb.com/api/json/v1/1/random.php");
      if (!raw_response.ok) { // check for the 404 errors
          throw new Error(raw_response.status);
      }
    const json_data = await raw_response.json();  //AWAIT
    let data = json_data.meals[0];

    console.log(data);
  }
  catch (error) { // catch block for network errors
      console.log(error); 
  }
}
RandomImage();


//(Example 2 : returning another promise)
console.log("1 is working");
console.log("2 is working");
  var AsyncFunction = async() => {
    var x = new Promise((resolve,reject) => {
        setTimeout(() => resolve("3 is working"), 3000);
    });
    var result = await x;
    return result;
  }
AsyncFunction().then(resolved => console.log(resolved));
console.log("3 is working");
