https://levelup.gitconnected.com/9-tricks-for-kickass-javascript-developers-in-2019-eb01dd3def2a If you’re still stuck in callback hell, 2014 wants its code back. Just don’t use callbacks, unless it is absolutely necessary, for example required by a library or for performance reasons. Promises are fine, but they’re a bit awkward to use if your codebase gets bigger. My go-to solution nowadays is async / await, which makes reading and improving my code a lot cleaner. In fact, you can await every Promise in JavaScript, in case a library you’re using is returning a Promise, simply await it. In fact, async/await is just syntactical sugar around promises. To make your code work, you only need to add the async keyword in front of a function. Here’s a quick example:

async.js
content_copyfile_download
async function getData() {
    const result = await axios.get('https://dube.io/service/ping')
    const data = result.data
    
    console.log('data', data)
    
    return data
}

getData()
