Return response from Axios and assign it to a variable

I'm trying to get something simple done with Axios but no luck. I want to get a response back from Axios call and assign it to a variable and do something with it next outside of the function block.

const axios = require("axios");
var posts;
(async () => {
  const allPosts = await axios.get("http://jsonplaceholder.typicode.com/posts");
  posts = allPosts;
})()
// do something with posts here

I know because the func is async we get to // do something with posts here first but then how we can work with the response outside of async function

Given this is node, and not React as the original tag suggested, it could be as easy as:

const axios = require("axios");
var posts;
await (async () => {
  const allPosts = await axios.get("http://jsonplaceholder.typicode.com/posts");
  posts = allPosts;
})();
// do something with posts

You can consider use callback function, like below code snippet:

const axios = require("axios");

(async () => {
  const allPosts = await axios.get("http://jsonplaceholder.typicode.com/posts");
  someThingYouWantToDo(allPosts);
})()

const someThingYouWantToDo = (posts) => {
  console.log(posts);
};

Usually you would assign posts to a state variable inside the async function right after receiving the data, and that would trigger a re-render. Or you would call a redux dispatch action to set the value in redux and redux would update the props. So in short, it's the usual React way: update state or props to render the view, use componentDidUpdate for any additional logic. For example:

const axios = require("axios");
var posts;
(async () => {
  const allPosts = await 
  axios.get("http://jsonplaceholder.typicode.com/posts");
  posts = allPosts;
  this.setState({
    posts,
  })
})()
