JavaScript async/await

JavaScript async/await
We use the async keyword with a function to represent that the function is an asynchronous function. The async function returns a promise.

The syntax of async function is:

async function name(parameter1, parameter2, ...paramaterN) {
// statements
}

Here,
- name - name of the function
- parameters - parameters that are passed to the function

Example: Async Function

// async function example
async function f() {
  console.log('Async function.');
  return Promise.resolve(1);

}
f();

Output

Async function.

In the above program, the async keyword is used before the function to represent that the function is asynchronous.

Since this function returns a promise, you can use the chaining method then() like this:


async function f() {
  console.log('Async function.');
  return Promise.resolve(1);

}
f().then(function(result) { 
  console.log(result)
});

Output

Async function
