Q:

How to call an async function

I want the console to print '1' first, but I am not sure how to call async functions and wait for its execution before going to the next line of code.    
const request = require('request');

async function getHtml() 
{
    await request('https://google.com/', function (error, response, body) {
    console.log('1');
  });

}

getHtml();
console.log('2');

Of course, the output I'm getting is 
2
1

A:

according to async_function MDN

Return value
A Promise which will be resolved with the value returned by the async function, or rejected with an uncaught exception thrown from within the async function.

async function will always return a promise and you have to use .then() or await to aaccess its value

async function getHtml() {
  const request = await $.get('https://jsonplaceholder.typicode.com/posts/1')  
  return request
}

getHtml()
  .then((data) => { console.log('1')})
  .then(() => { console.log('2')});
  
// OR 

(async() => {
  console.log('1')
  await getHtml()  
  console.log('2')
})()
