JavaScript - Missing Syntax Error

I discovered this weird thing by an accident. I was writting some issue on GitHub and, as you know, to use some language highlighting in GitHub post you should encapsulate it in tripple grave accent. For example, if you want to use JavaScript, you should do this:

```JavaScript
// Your code
```

It will use JavaScript highlighting in your code snippet.

However, while I was writtin a post there, I accidentally copied whole code snipped from edit mode (including grave accents) and pasted it in js file. I've forgotten to remove accents, though. This is my code in js file:

function test(){
  ```JavaScript
  console.log(1);
  ```
}

It should be syntax error, of course. But, what surprises me is that Node.js compiled it without any errors. I couldn't believe. No cyntax error at all. How is this even possible?

So, I suppose tripple grave accent has special meaning in JavaScript (maybe multiline string like in Python?). I searchen on internet, but I found nothing. Why is EcmaScript allowing this? What is an example use of it?
