How to convert asynchronous code to synchronous?

Question

Node.js

Hello. I'm currently trying to use the PhantomJs wrapper for node - horseman .
Here is an example code:

const Horseman = require('node-horseman');
const users = ['PhantomJS', 'nodejs'];


users.forEach((user) => {
    console.log(5)
    const horseman = new Horseman()
      .open(`http://twitter.com/${user}`)
      .text('.ProfileNav-item--followers .ProfileNav-value')
      .click('a')
      .then((text) => {
        console.log(6);
      })
      .close();
});

Gives me:

5
5
6
6

But you must:

5
6
5
6

That is to make this code synchronous.
Hope for help here.

Answer 1

Before it's too late, try not to use PhantomJs (it is no longer particularly supported), there is https://github.com/GoogleChrome/puppeteer from Google, it will be cooler)

Answer 2

you can make it synchronous only if you remove everything asynchronous (horseman), but then this code will be useless.
What you need is not synchronicity, but correct order.
Use either promise chaining or async/await in the loop instead of forEach (if phantomjs supports it).

Answer 3

Use async / await.
