I am beginner at javascript so please bear with me. I wonder how to put async() event in the right way.
I have 2 code snippets that I want to execute asynchronously and not synchronously. The code snippets use a library that do HTTP requests so that is out of my control.

So I like the 2 code snippets to execute in parallell somehow. What I have are those 2 code snippets and I also think I understand that I only want to declare the first 2 lines once as those lines takes time:

```
'use strict';
 const ccxt = require ('ccxt');

```

The 2 code snippets are the below

**Code snippet1:**

```js
'use strict';
const ccxt = require ('ccxt');

(async () => {
            try{
       const exchange = new ccxt.one({ enableRateLimit: true })
       const tickers = await exchange.fetchTickers()
       const obj = { tickers }
       const fs = require('fs');
       fs.writeFile("/myproject/file1.txt", JSON.stringify(obj), function(err) { });
       }catch{}
}) ()
```

**Code snippet2:**

```js
'use strict';
const ccxt = require ('ccxt');

(async () => {
            try{
       const exchange = new ccxt.two({ enableRateLimit: true })
       const tickers = await exchange.fetchTickers()
       const obj = { tickers }
       const fs = require('fs');
       fs.writeFile("/myproject/file2.txt", JSON.stringify(obj), function(err) { });
       }catch{}
}) ()
```
