saving information from a GET call into an array

Question

saving information from a GET call into an array

In my current project, I am facing an issue with storing tweet IDs for later use. Here is the code snippet I am using:

let twit = require('twit');
let config = require('./config.js');

const T = new twit(config);

let retweetIDs = [];

const promise = T.get('statuses/user_timeline', {screen_name: 'someusername', count: '1'});

promise.then(res =>{
    let id = res["data"][0]["id"];
    retweetIDs.push(id)
});

console.log(retweetIDs)

When I check the console.log(), it returns an empty array []. It seems like a timing issue due to JavaScript being asynchronous, but I'm not sure how to solve it. Any advice or guidance on this problem would be greatly appreciated.

To make the code more efficient, simply place console.log inside the then block:

promise.then(res =>{
    let id = res["data"][0]["id"];
    retweetIDs.push(id);
    console.log(retweetIDs);
});

For a smoother execution, consider using async-await for synchronous code like so:

let twit = require('twit');
let config = require('./config.js');

(async () => {
    let retweetIDs = [];

    const
        url = 'statuses/user_timeline',
        params = { screen_name: 'someusername', count: '1' },
        result = await new twit(config).get(url, params),
        { id } = result.data[0];

    retweetIDs.push(id);

    console.log(retweetIDs);
})();
